European Window Blind Ready-Made Sizes: B2B Sourcing Guide
Europe is the opposite of North America for sizing. Every country uses centimeters, but no shared size standard exists, and a single ready-made program cannot cover the region. Germany runs on a 12.5 cm DIN grid, the UK still stocks imperial-converted heights, France has tall Haussmann windows, Southern Europe stays shorter and wider for sun control, and the Nordics go tall for light. The practical consequence for a buyer is that ready-made blinds must be selected country by country rather than by one European size sheet. The tables below are the stock grids we quote against; sizing data in this guide reflects current ready-made programs as of October 2026.
Key takeaways
- Europe is fully metric but fragmented: Germany uses a 12.5 cm (1/8 m) grid under DIN 18055, France a 10 cm grid, and the UK millimeters with no mandatory grid - so one stock size list will not work across borders.
- The UK is the outlier on heights: it still sells 137 cm (54"), 183 cm (72"), 210 cm and 229 cm (90") ready-made blinds because of imperial retail heritage.
- Windows follow climate and history: France and the Nordics need tall stock (200-250 cm), while Southern Europe is shorter and wider with little demand above 250 cm.
- Category and country combos differ - roller, zebra, aluminium venetian and cellular each have their own best-selling size per market - so stock by category and country, not by a generic European range.
Why sizing fragments across Europe
Four forces split European window sizes apart:
- Divergent building codes. Germany works on the DIN 18055 standard system; the UK follows Building Regulations without mandatory size standards; France uses DTU norms with lighter enforcement; Southern and Nordic countries each go their own way.
- Different architectural history. The UK has a large Victorian and Edwardian stock (though new builds are fairly standard); German post-war housing is highly standardized; French Haussmann buildings have uniform tall proportions; Southern European old towns are dense with smaller windows.
- Climate shapes the window. High-latitude Nordics maximize light with taller windows; hot Southern Europe uses smaller, shorter openings to shade sun; temperate Western Europe sits between.
- Metric yes, grid no. All of Europe uses centimeters and millimeters, but the grids differ - Germany 12.5 cm, France 10 cm, the UK millimeters with no mandatory grid.
Germany: DIN 18055 and the 12.5 cm grid
Germany is the most standardized window market in Europe, built on DIN 18055 and a 12.5 cm (1/8 meter) grid.
German structural rough openings (Baurichtmaß) step up on the 1/8 meter grid:
- Standard widths: 51, 76, 101, 126, 151, 176, 201, 226, 251 cm
- Standard heights: Same 1/8 meter grid, from 51 cm to 251 cm
Actual window dimensions after installation clearance:
| Window Type | Common Sizes (WxH, cm) | Use Case |
|---|---|---|
| Basement/small window | 50x50, 60x40, 80x50 | Basement, utility room |
| Kitchen window | 80x60, 90x60, 100x60 | Kitchen (above countertop) |
| Single-sash standard | 60x120, 80x120, 100x120 | Bedroom, study |
| Double-sash standard | 120x120, 130x120, 140x120 | Living room, bedroom |
| Large double-sash | 150x120, 150x150, 200x150 | Large living room, tall window |
| Window door (Fenstertür) | 80x210, 90x210 | Balcony door |
German residential sill height is about 85-90 cm and ceiling height about 250-260 cm. Bedrooms and studies are mostly single-sash; living rooms double-sash or large windows.

German retail ready-made rollers usually step in 10 cm widths (40/50/60/70/80/90/100/120/150 cm), with some brands adding 5 cm increments in the middle range. Ready-made heights commonly come in four tiers: 150/180/200/250 cm.
United Kingdom: new-build standard and imperial heights
UK new-build housing is relatively standardized and is the main ready-made target; the older Victorian stock is where custom work concentrates.
| Window Type | Common Sizes (WxH, mm) | Share |
|---|---|---|
| Casement window | 600x900 | ~40% of replacement orders |
| Casement window | 900x1200 | ~20% |
| Casement window | 1200x1200 | ~15% |
| Bedroom window | 600x900 to 1200x1500 | Varies by room size |
Common ready-made blind sizes in the UK:
| Category | Common Widths (cm) | Common Heights (cm) | Notes |
|---|---|---|---|
| Roller blinds | 45, 60, 90, 120, 150, 180 | 100, 137, 150, 160, 183, 200, 210, 229 | 137 cm / 183 cm are imperial conversions (54" / 72") |
| Zebra blinds | 60, 90, 120, 150 | 150, 180, 200, 210 | |
| Aluminium venetian | 45, 60, 90, 120 | 100, 130, 150, 180 | |
| Faux wood venetian | 60, 90, 120, 150 | 130, 150, 180 | Faux wood venetian has high acceptance in the UK |
The UK ready-made market still sells imperial-converted heights - 137 cm (54 in), 183 cm (72 in), 210 cm (82.7 in) and 229 cm (90 in). These sizes are common in UK retail channels such as Dunelm and Argos.
France: tall windows on a 10 cm grid
France follows the NF DTU 36.5 norm for a relatively unified size system.
| Window Type | Common Sizes (WxH, cm) | Use Case |
|---|---|---|
| Single-sash (1 vantail) | 60x75, 80x95, 100x115, 120x135 | Bedroom, kitchen, bathroom |
| Double-sash (2 vantaux) | 100x115, 100x125, 120x115, 120x125, 120x135 | Living room, master bedroom |
| Large double-sash | 140x120, 140x135, 160x120 | Large living room |
| Window door (porte-fenêtre) | 60x215, 80x215, 90x215 | Balcony door |
| Kitchen window | 60x60, 80x60, 100x60 | Above countertop |
| Bathroom window | 60x60, 60x75, 75x60 | Small, high window |
French retail roller and zebra blind specifications:
- Widths: 45, 60, 75, 90, 100, 120, 150, 180 cm
- Heights: 100, 120, 150, 180, 200, 220, 250 cm
- Best-selling combos: 60x150, 90x150, 120x180, 150x200
Haussmann buildings in cities such as Paris carry tall windows (typically 200-250 cm), which drives real demand for ready-made blinds above 200 cm.
Southern Europe: shorter and wider
Hot climates push Southern European design toward smaller, denser openings to cut direct sun, so windows run shorter and wider overall.
| Window Type (Spain/Portugal) | Common Sizes (WxH, cm) |
|---|---|
| Single-sash | 60x80, 80x100, 100x120 |
| Double-sash | 120x100, 120x120, 150x120 |
| Kitchen window | 60x60, 80x60 |
| Bathroom window | 40x60, 60x60 (small, high) |
| Window Type (Italy) | Common Sizes (WxH, cm) |
|---|---|
| Double-sash standard | 100x120, 120x120, 120x140 |
| Large double-sash | 140x140, 150x150 |
| Single-sash | 60x100, 80x120 |
Spanish and Portuguese residential windows are generally 10-20 cm shorter than Nordic ones. Venetian blinds (aluminium and faux wood) have high ready-made acceptance, because buyers here adjust light rather than chasing full blackout.
- Widths: 45, 60, 80, 100, 120, 150 cm
- Heights: 100, 120, 150, 180, 200 cm (little demand above 250 cm)
- Best-selling combos: 60x150, 80x150, 100x180, 120x180
Nordic Europe: taller and larger
Short winter daylight pushes Nordic design toward bigger windows, so stock runs taller than anywhere else in Europe.
| Country | Common Double-Sash Sizes (WxH, cm) | Feature |
|---|---|---|
| Sweden | 120x140, 150x150, 180x180 | Large windows, high ceilings |
| Norway | 120x140, 150x160, 180x180 | Similar to Sweden |
| Denmark | 100x120, 120x140, 150x150 | Slightly smaller than Sweden/Norway |
| Finland | 120x140, 150x150, 180x180 | Similar to Sweden |
- Widths: 60, 80, 100, 120, 150, 180 cm
- Heights: 150, 180, 200, 250 cm (demand above 200 cm is far higher than in Southern Europe)
- Best-selling combos: 120x200, 150x250
- Key categories: Cellular/honeycomb (energy efficiency fits the market), roller and zebra
- Mechanism: Cordless is mainstream; Nordic safety standards are strict

Bottom line
Stock Europe by country, not by a single size sheet. Lead with Germany's 12.5 cm grid, keep the UK's imperial-converted heights in mind, hold tall stock for France and the Nordics, and keep Southern Europe short and wide. Yuehua has supplied window blinds since 1998 from BSCI-audited production, and we build the roller, zebra, aluminium venetian and cellular lines these tables cover.
For the inch side of the Atlantic, the North America size guide shows how the four-digit inch code works. If safety is part of the same buy, the EU blind compliance guide covers CE and the cord-safety rules the Nordics enforce. On the product side, our honeycomb shade is the thermal line that fits the Nordic and German energy-efficiency channel.
