The Curtain Market in Numbers

Start with an uncomfortable fact, because a lender will find it anyway: there is no single agreed market size for curtains. Research houses draw the boundary in different places, and the answers diverge by nearly a factor of two. Fortune Business Insights values the global window covering market at $15.07 billion in 2025, rising to $15.82 billion in 2026 (Fortune Business Insights, 2025). Research Nester puts curtains and window blinds at $26.1 billion in 2025, crossing $44.58 billion by 2035 (Research Nester, 2025). Global Market Insights sizes window coverings at $17.6 billion in 2025 growing to $34.4 billion by 2034 at a 7.7% CAGR (Global Market Insights, 2025), while Custom Market Insights reports $27.1 billion in 2025 reaching $58.5 billion by 2034 at 8.99% (Custom Market Insights via GlobeNewswire, 2025).

Those four figures are not contradictions. They are four different questions. The lower numbers count finished window coverings sold at retail. The higher ones fold in blinds, shutters, hardware and contract supply. What every one of them agrees on is direction: mid-to-high single-digit annual growth, sustained into the 2030s. So write your plan the way a credit analyst reads it. Name the source, name the definition, and pick the one that matches the business you are actually building. A workroom sewing pinch-pleat pairs for private clients in Surrey does not participate in the motorised-shutter half of a $27 billion figure, and claiming it does is how a plan loses its credibility on page three.

The growth is concentrated, not evenly spread. Value is moving toward motorised tracks, certified blackout and thermal linings, and specified contract work, all three of which are things a general home-textiles retailer cannot easily do and a skilled workroom can. That is the real opportunity in this trade in 2026. Not curtains as such, which anyone can buy ready-made from a supermarket for a fraction of your cost, but the parts of the job that need measuring, judgement, certification and a person on a ladder.

Your plan should therefore open with a segment claim rather than a market claim. Something like: "we address the made-to-measure and contract segment of a window-coverings category valued at $17.6 billion globally in 2025 and growing at 7.7% annually, in a 12-mile catchment containing roughly 41,000 owner-occupied households." The first half is sourced. The second half is yours. Investors and lenders care much more about the second half, and most curtain plans never write it.

One more number worth putting in the plan: NAICS 314120, Curtain and Linen Mills, is the classification a US lender will file you under, and the SBA size standards table treats businesses with 750 employees or fewer in that code as small (IBISWorld, NAICS 314120). You will never be near that ceiling, which is the point: the whole trade qualifies for SBA-backed lending, and a plan that names the code correctly on the first page signals that you have done this before. If your business is primarily retail rather than fabrication, your lender may prefer a retail window-treatment code instead. Ask before you file, not after.

Three Curtain Businesses, Three Cost Bases

"Curtain business" describes at least three distinct companies. They share a product and almost nothing else. Their capital needs differ by an order of magnitude, their gross margins differ by twenty points, and the thing that limits their growth is different in each case. Pick one before you write a word of the plan, because the financial model is not portable between them.

Read the "binding constraint" row twice. It is the row most plans get wrong. A workroom founder typically writes a marketing plan aimed at generating more enquiries, when the business is already turning work away because there are only so many hours in a fitter's week. The correct plan for that business is a pricing plan, not a marketing plan. Push the average order value up, drop the low-value jobs, and revenue rises without a single extra lead.

The online model is the one founders underestimate most, and the reason is physical rather than commercial. Curtains ship on volumetric weight, meaning the courier prices the box, not the fabric. A pair of lined curtains is light and enormous, which is the worst possible combination for a freight quote. That is why theoretical gross margins above 50% on curtains routinely settle far lower once real operations are applied. If your plan has an online channel, the freight line has to be modelled per parcel, not as a percentage of revenue.

Hillarys is worth studying for a different reason. It does not publish prices online at all; the route to a quote is an in-home appointment where an advisor measures the window and prices on the spot. That is not obstruction, it is margin defence. It moves the conversation from price to fit and removes the customer's ability to line you up against a spreadsheet of competitors. An independent workroom can copy this exact mechanic on day one at zero cost, and most do not.

What It Costs to Open the Doors

The realistic range is $18,000 to $165,000 in the US and £12,000 to £120,000 in the UK, and the spread is almost entirely explained by one decision: whether you take a lease. A home workroom with an industrial machine and a proper cutting table sits at the bottom. A high-street showroom with dressed windows and opening stock sits at the top. Everything else on the list moves by a few thousand.

Line by line, with the items founders forget

• Workroom lease deposit + first quarter: $0–$24,000 (£0–£15,000). Zero if you start at home, which a large share of successful independents do.
• Cutting table, industrial machines, steamer, overlocker, blind bench: $6,000–$28,000 (£4,500–£20,000). A 3m by 1.5m table is the minimum for full-drop work; buying a domestic-size table is the classic false economy.
• Fabric pattern books and sample stands: $1,500–$9,000 (£1,200–£7,000). Suppliers rarely hand these out free to a business with no trading history, and without them you cannot sell.
• Showroom fit-out and window displays: $15,000–$60,000 (£10,000–£45,000). Retail model only. Skip this line and your top-of-range halves.
• Van, ladders, measuring and installation kit: $4,000–$32,000 (£3,000–£25,000). A used van at the bottom, a new liveried one at the top.
• Quoting software, website, e-commerce build: $600–$8,000 (£500–£6,000).
• Public and product liability + goods-in-transit cover: $900–$3,500/yr (£600–£2,600/yr). Goods-in-transit is the forgotten one: a £2,000 pair of curtains ruined in the back of a van is your loss, not the client's.
• Opening fabric and hardware stock: $3,000–$20,000 (£2,500–£16,000).
• Working capital, 3 months: $8,000–$40,000 (£6,000–£30,000).

Funding routes that actually fit this trade

In the US, the SBA 7(a) programme lends up to $5 million with terms as long as 25 years and is the standard route for a curtain workroom or showroom. Across FY2024 the programme approved roughly $31 billion over approximately 50,000 to 60,000 loans (Lendio, SBA 7(a) guide). File under NAICS 314120 if you fabricate. Two things get curtain applications declined: no personal industry experience evidenced anywhere in the plan, and a forecast whose gross margin is asserted rather than derived. Our bespoke plan service builds the forecast so the gross margin falls out of the fabric-yield maths, which is what a credit analyst is actually looking for.

In the UK, the Start Up Loan scheme offers up to £25,000 per founder at 6% fixed with free mentoring, and two co-founders can stack to £50,000. For a two-person workroom that is often the entire equipment budget. Beyond that, asset finance on the van and the machines is usually cheaper and easier than an unsecured overdraft, because the lender can see the collateral. Similar routes exist in Canada through BDC, in Australia through the major bank small-business programmes, and in the UAE through the Khalifa Fund.

One funding nuance specific to curtains: because the customer pays a deposit at order and the balance on fit, a healthy workroom is cash-positive on the job cycle. Say that explicitly in the plan. Most lenders assume a manufacturing business is cash-hungry, and showing them a positive working-capital cycle materially changes the conversation about how much you need to borrow.

Where You Trade Changes the Price

National averages are actively misleading in this trade, because the same pair of curtains has two quite different prices twenty miles apart. Fabric costs the same in Cheshire as it does in Chelsea. Labour, rent and, above all, willingness to pay do not. Build your revenue line from a local price band, not a national one.

United Kingdom

• Central and South West London: £450–£900+ per window. A single window at 100cm x 150cm has been quoted at £450 by a national brand, and interlined work in period properties runs well past that. Bay windows and 3m drops are routine, which lifts both fabric and fitting time.
• Home Counties and commuter belt: £350–£600 per window. The densest concentration of made-to-measure demand per household in Britain, and the most competitive.
• Northern England, Midlands and Scotland: £220–£400 per window. The published national band of £300–£400 for quality made-to-measure sits squarely here (Stitched, curtain budgeting guide). Volume compensates for the lower ticket.
• Rural and coastal: £200–£380 per window, with travel time as the hidden cost. A 90-minute round trip to measure and a second one to fit turns a £300 job into a loss.

United States

• Custom drapery panels nationally: $300–$1,000+ per panel, driven mainly by fabric, with linen, silk and velvet at the top and polyester blends at the bottom (Blinds Chalet, drapery pricing guide).
• Installation labour: $15–$50 per window, or $140–$400 for a typical job (HomeAdvisor, 2025 blind installation data). Materials plus installation across all treatment types runs $50–$1,000 per window (Angi, 2026 window treatment cost data).
• Franchise benchmark: Budget Blinds sits at $200–$1,000 per window for materials only. That is the number your local customer will have in their head, and it is the number you are being compared against whether you like it or not.
• Metro premium: Coastal metros support the top of every band, and the same job in a lower-cost inland market clears 30–40% less. If you plan multi-market expansion, model each market separately or the blended forecast will be wrong in both.

There is a second regional variable that has nothing to do with wealth: housing stock. A postcode full of Victorian terraces with tall sash windows and bays is worth roughly double a postcode of new-build flats with standard apertures, because the fabric quantities are larger and the work is not something the customer can substitute with a ready-made pair. Map your catchment by property age, not just household income. It is a five-minute exercise on any land registry or assessor dataset and almost nobody in this trade does it.

Then there is contract work, which ignores the residential map entirely. Hotels, care homes, schools, student accommodation and offices buy on specification and repeat. The order values are large, the fabric is certified, the payment terms are worse, and the competition is a fraction of the residential field. Any curtain plan aiming above 20% net margin needs a contract channel in it.

How the Money Actually Works

Here is the number that decides whether your curtain business makes money, and it is not in any of the competing guides: fullness ratio. Curtains are not quoted from the width of the window. They are quoted from the width of fabric needed to dress it, which is the track width multiplied by a fullness ratio, plus hems and returns, then divided by the usable fabric width and rounded up to whole widths. Get this wrong and you are not making 50% gross, you are making 30% and wondering why.

The yield calculation, worked

Take a 250cm track, pinch pleat at 2.5 fullness, on a 137cm fabric. Required flat width is 250 x 2.5 = 625cm, plus roughly 16cm of side hems and a 5cm return, so 646cm. Divide by 137cm and you need 5 widths, not the 2 that the finished window suggests. Now take a 2.4m finished drop and add 25cm for hem and heading: a 2.65m cut drop. Five widths at 2.65m is 13.25m of fabric. At £28/m that is £371 in cloth before lining, tape, hooks, track or a single minute of labour.

Now add pattern repeat. If that fabric has a 64cm repeat, every cut drop must round up to a whole number of repeats: 2.65m becomes 3.2m, so 16m of fabric rather than 13.25m. That is £448, a 21% increase, from a variable that appears nowhere on the customer's quote. Every quoting error in this trade lives in that paragraph. It is also why a well-built forecast derives gross margin from yield rather than assuming a percentage, and why lenders who know the trade look for it.

What that means at the P&L level

Take a two-fitter workroom quoting five jobs a week at an average order value of £1,150. That is roughly £299,000 a year. Fabric and hardware at 38% of sales is £113,600. Making-labour at 17% is £50,800. Gross profit lands near £134,600, or 45%. Then the fixed costs: van, workroom rent, insurance, software, marketing and the owner's own time come to about £96,000. Operating profit is roughly £38,600, or 12.9% net.

That is an honest, unglamorous, entirely achievable number, and it is why the published range for this trade is 5% to 20% rather than the 50%-plus that gross margin tempts founders to write. Realised margins settle far below theoretical ones once operational reality is applied. If a plan in front of a bank claims 35% net on residential curtains, the bank has seen the trade before and will not believe it.

The four levers that actually move the number

• Attach the hardware. Track, poles, motorisation and fitting carry better margin than cloth and add £200–£600 to a job the customer was already committed to.
• Sell the lining up. Blackout and thermal interlining are a small fabric-cost increase and a large price increase, and the customer genuinely wants them. This is the highest-return upsell in the trade.
• Raise the floor, not the ceiling. Set a minimum order value and decline below it. A £280 job with two site visits consumes the same fitter hours as an £1,100 one.
• Add a contract account. One 40-room hotel refurbishment can equal a quarter of residential revenue at half the selling effort, and it repeats on a refurbishment cycle.

Seasonality is the last thing to model honestly. Curtain demand spikes ahead of Christmas and again in late spring, and dies in the height of summer. A flat monthly revenue line in your forecast tells any experienced reader that you have not run this business. Model the actual curve, show the summer trough, and show how you cover it. Contract work, which does not follow the domestic curve, is the usual answer.

Rules That Bind: Fire, Cords and Trading

There is no curtain licence anywhere. What binds this trade is product compliance, and it bites exactly where the money is: contract work and blinds. Two founders in ten get this wrong, and they find out at handover, when a fire officer rejects a hotel's drapery and the job is remade at your cost.

United States

• NFPA 701 flame propagation test. The International Fire Code treats curtains, draperies and similar surface coverings as decorative materials and generally requires NFPA 701 compliance in public spaces. Pass criteria: char length under 6.5 inches, after-flame of two seconds or less, and no flaming drips, measured after a 12-second flame exposure.
• Which test applies. Test Method 1 is the small-scale test for fabrics at 21 oz per square yard or lighter, including single-layer fabrics and multi-layer curtains sewn together. Test Method 2 is the large-scale test for anything heavier, which is where blackout linings land.
• There is no federal drapery flammability regulation. Authority sits with state and local government, which is why the requirement follows the jurisdiction, not the product.
• California is separate. Drapery used in California public spaces must use fabric registered with the State Fire Marshal under Title 19 of the California Code of Regulations, which is distinct from and additional to NFPA 701.
• Ordinary trading: state sales tax permit, local business licence, and in some states a contractor licence where installation counts as improvement work. Budget $0–$500 and up to six weeks.

The commercial lesson underneath all that: specify pre-certified fabric rather than treating it afterwards. Inherently flame-retardant cloth costs more per metre and costs nothing in risk. Topical treatment is cheaper up front and can be compromised by cleaning, which turns a compliant job into a non-compliant one two years later, on your reputation. Put the fabric specification policy in the operations section of your plan. It is exactly the kind of detail that separates a plan written by someone in the trade from one written by someone reading about it.

United Kingdom

• BS EN 13120 child safety. Every internal blind made or sold since February 2014 must have looped cords and chains either eliminated or made safe with an approved safety device.
• The cord rule, precisely. On any blind with a pull cord, there must be at least 150cm between the bottom of the cord and the floor, reduced to 60cm where a breakaway device is fitted.
• Where it applies. Safety devices are required in any location where children under 42 months may be present, which in practice means you fit them by default and never make a judgement call on a customer's household.
• Safety information must be supplied. The British Blind and Shutter Association's Make It Safe campaign is the reference point for the advice that goes out with the product.
• Ordinary trading: Companies House incorporation at £12–£50, VAT registration once turnover crosses the threshold, and public and product liability cover at £600–£2,600 a year.

Other jurisdictions

Australia operates a mandatory consumer product safety standard for corded internal window coverings, requiring cord-restraint devices, warning labelling and compliant installation, and it is enforced rather than advisory. Across the EU, EN 13120 is the harmonised internal-blind standard, and EN 13773 classifies the fire behaviour of curtains and drapes used in public buildings, which is the equivalent hurdle to NFPA 701 for anyone selling contract drapery into European hotels or public buildings. If your plan includes export or a second market, name the standard for that market by number. Lenders and investors read that as operational competence, and it costs you one sentence.

Trade Language a Lender Will Expect You to Use

Curtain making has a vocabulary, and using it correctly in your plan is a cheap, high-signal way to demonstrate you have done the work. These eight terms carry real financial weight, which is why they belong in the operations and gross-margin sections rather than in a footnote.

• Fullness ratio. The multiple of track width used to calculate flat fabric width. Roughly 2.0 for pencil pleat, 2.0 to 2.5 for pinch pleat, 2.2 to 2.5 for wave. This single number drives your cost of goods.
• Cut drop. The finished drop plus hem and heading allowance, usually around 25cm. Then rounded up to the next whole pattern repeat, which is where patterned jobs quietly overrun.
• Pattern repeat. The vertical distance before a design restarts. A 64cm repeat on a 2.65m cut drop forces you to buy 3.2m, adding around 21% to fabric cost on that job.
• Interlining. A soft layer between face fabric and lining. It adds weight, drape, insulation and about 30–40% to the price, and it is the highest-conversion upsell in residential work.
• Buckram. The stiffened band sewn into the heading that holds a pleat's shape. Cheap material, and the reason a pleat either looks bespoke or looks homemade.
• Stack-back. How much wall the curtain occupies when fully open. Get it wrong and you have blocked a third of the customer's window and daylight, which is a remake, not a complaint.
• Return. The section that wraps from the track face back to the wall, typically 5cm. Small in centimetres, and the difference between a light-tight blackout job and a refund.
• Contract drapery. Curtains specified for a commercial or public building, requiring certified fabric under NFPA 701 or EN 13773. Longer payment terms, larger orders, far fewer competitors.

One tooling note, since it comes up in every discovery call: quoting is where independents lose money, and there are trade-specific calculators built for exactly this, InterioApp among them (InterioApp, how to start in the curtain business). Pair one with Xero or QuickBooks for the books and Shopify if you run an online cut-to-size line. Name the stack in your operations section. It is a small thing that tells a reader you have thought about how quotes become invoices.
