Asia-Pacific & Emerging Markets Window Blind Ready-Made Sizes: B2B Sourcing Guide
Asia-Pacific has the widest gap in ready-made blind maturity of any region. Australia and New Zealand are the one large, stocked retail market - Spotlight, Bunnings, IKEA, Kmart and The Warehouse all carry standard venetian, roller and honeycomb ranges. Japan, Korea, China, India and most of Southeast Asia are predominantly made-to-measure, with IKEA carrying only a small ready-made selection. The buying rule is therefore not a regional size sheet: build ready-made volume around Australia and New Zealand, and run the rest as custom while watching IKEA and similar retail channels. The tables below reflect current programs as of October 2026.
Key takeaways
- Only Australia/New Zealand is a bulk ready-made market in Asia-Pacific; everywhere else - Japan, Korea, China, India, Southeast Asia - blinds are made to measure, so do not force a ready-made program there.
- AU/NZ ready-made grids step in 30 cm widths: aluminium venetians 60-210 cm wide with 150/210 cm drops, timber venetians up to 210 cm wide and 240 cm drop, and rollers 60-210 cm wide with 150-210 cm drops.
- Japan custom work demands extreme precision - tolerances within +/-1 mm, ordered in 0.5 or 1 cm steps across 15-300 cm widths - which sets it apart from the rest of the region.
- Korean apartments center on large balcony windows (a 200x230 cm double-panel living-room balcony unit is most common), while China follows GB/T 5824 openings and India the CPWD 90x120 cm room window.
Why sizing splits across the region
Five forces drive the difference:
- Multiple standards systems. Japan uses JIS, Korea KS, China GB/T 5824, India CPWD, Australia/New Zealand AS/NZS, and Southeast Asia has no unified standard.
- Maturity gap. Australia and New Zealand have the region's deepest ready-made venetian, roller and honeycomb ranges; Japan, Korea, China, India and most of Southeast Asia are made-to-measure, with only IKEA and similar international retailers carrying a small selection.
- Ceiling height. Japanese and Korean apartments run 2.3-2.7 m, China and Southeast Asia 2.8-3.2 m, Australia/New Zealand 2.4-2.7 m.
- Window type. Korean apartments feature balcony sliding windows; Japan leans waist-height and floor-to-ceiling units; China and Southeast Asia favor sliding; Australia/New Zealand use sliding and awning windows.
- Income and channel. Japan, Australia/New Zealand, Korea and Singapore run mature custom channels; China, Malaysia and Thailand are middle-income; India, Indonesia, Vietnam and the Philippines are emerging with developing channels.
Japan: custom-first, a small IKEA ready-made range
The Japanese market is predominantly custom. Ready-made venetians, rollers, honeycombs and zebras are virtually nonexistent - nearly everything is made-to-order (order). IKEA Japan is one of the few ready-made channels, selling venetians (VECKLARFLY) and rollers.
| Window Type | Common Sizes (WxH, cm) | Usage |
|---|---|---|
| Waist-height window | 100x110, 120x110 | Bedroom, study (sill height ~90cm) |
| Floor-to-ceiling window | 100x200, 100x210, 120x200, 120x210 | Living room, balcony door |
| Small/bathroom window | 60x60, 60x90 | Bathroom, kitchen |
| Bay window | 100x110, 120x110 | Bay window |
Ready-made blind sizes (IKEA channel):
| Category | Common Width (cm) | Common Height (cm) | Best-Selling | Retail Channel |
|---|---|---|---|---|
| Ready-made venetian blind | 60, 100, 120, 140 | 155 | 60x155, 100x155, 120x155 | IKEA |
| Ready-made roller blind | 90, 100, 140 | 190, 195 | 90x190, 100x195, 140x195 | IKEA |
| Ready-made honeycomb shade | 140 | 195 | 140x195 | IKEA |
IKEA Japan's VECKLARFLY venetians come in 60x155, 100x155, 120x155 and 140x155 cm; rollers in 90x190, 100x195 and 140x195 cm; TRIPPEVALS honeycombs in 140x195 cm. IKEA is a small share of the Japanese market, where consumers still order custom through specialty blind shops. Custom venetians, rollers, honeycombs and zebras in Japan typically run 15-300 cm wide and 11-300 cm high, ordered in 0.5 or 1 cm steps, with tolerance expected within +/-1 mm.
Korea: custom-first, balcony windows dominate
Korea is predominantly custom with a tiny ready-made retail market. Korean apartments are defined by balcony windows (berandachang) - living rooms usually have large balcony sliding doors that need relatively large blind sizes. IKEA Korea is one of the few ready-made channels.
| Window Type | Common Sizes (WxH, cm) | Usage |
|---|---|---|
| Living room balcony window (small) | 200-250x150 | Small apartment living room |
| Living room balcony window (large) | 300-400x200 | Medium apartment living room |
| Front living room window | 400-500x230 | Large apartment / luxury home living room |
| Balcony window | 150x200-230 | Bedroom balcony |
| Bedroom window | 140x230, 170x230 | Master bedroom, small room |
| Bathroom window | 60-90x60-90 | Bathroom |
A 200x230 cm double-panel (yanggae) living-room balcony window is the most common Korean spec. Master-bedroom large windows run 140x230 or 170x230 cm, and small-room windows 140x230 cm single-panel (pyeonggae). Actual apartment cases show exterior living-room balcony units around 214x185 cm and interior around 180x206 cm. IKEA Korea sells the same VECKLARFLY venetians (60x155 to 140x155 cm) and rollers (90x190, 100x195 cm), but the market stays custom-first through specialty shops and online custom platforms.
Australia and New Zealand: the mature ready-made market
Australia and New Zealand run the most mature ready-made venetian, roller and honeycomb markets in the region. Spotlight, Bunnings, IKEA, Kmart, Big W and The Warehouse all carry broad ready-made ranges alongside made-to-measure. Windows follow AS/NZS 2047.
| Window Type | Common Sizes (WxH, cm) | Usage |
|---|---|---|
| Bathroom window | 60x60, 60x90 | Bathroom |
| Kitchen window | 90x120, 120x120 | Kitchen |
| Bedroom window | 120x120, 120x150 | Bedroom |
| Living room window | 150x150, 180x150, 240x210 | Living room |
| Floor-to-ceiling / door window | 180x210, 240x210 | Balcony door, floor-to-ceiling window |

| Timber venetian blind | 60, 90, 120, 150, 180, 210 | 137, 150, 210, 240 | 90x150, 120x210, 150x240 | Spotlight |
| PVC venetian blind | 60, 90, 120, 150 | 150, 210 | 60x150, 90x150 | The Warehouse, Kmart |
Spotlight aluminium venetians start at 60 cm wide, stepping in 30 cm up to 210 cm, with 150 and 210 cm drops. Timber venetians (KOO 50mm Timber) top out at 210 cm wide and 240 cm drop, starting at 60 cm wide and 137 cm drop. IKEA VECKLARFLY venetians run 60x155 to 140x155 cm. The Warehouse sells Homeworks PVC cordless venetians (25 mm slat), and Spotlight also offers in-store cut-to-size.
Ready-made roller sizes:

Australian ready-made roller standard widths are 600, 900, 1200 and 1800 mm with 1500-2100 mm drops. Bunnings, Spotlight, IKEA and The Warehouse all sell blockout and light-filtering rollers; The Warehouse sells the Homeworks Fleet blockout roller. IKEA ready-made rollers run 90x190, 100x195 and 140x195 cm.
Ready-made honeycomb and roman:
| Category | Common Width (cm) | Common Drop (cm) | Retail Channel |
|---|---|---|---|
| Ready-made honeycomb shade | 60, 100, 140 | 155, 195 | IKEA |
| Ready-made roman blind | 50-210 | From 90 | NZ online retailer |
IKEA sells TRIPPEVALS honeycombs globally, such as 140x195 cm. A New Zealand online retailer sells Studio One Matilda roman blinds from 50 to 210 cm wide with lengths from 90 cm. Ready-made zebras are rare in AU/NZ retail and are mostly custom. Custom rollers can run up to 2900 mm wide by 3000 mm high, and custom venetians up to 2500 mm wide; Spotlight, Bunnings and NZ Blinds offer both ready-made and made-to-measure.
China: custom-first under GB/T 5824
China runs GB/T 5824-2021, Building Window and Door Opening Size Series. Preferred opening widths are 600, 900, 1200, 1500, 1800 and 2100 mm, and preferred heights 600, 900, 1200 and 1500 mm. The market is predominantly custom, with ready-made venetians, rollers, honeycombs and zebras virtually absent; IKEA China is one of the few ready-made channels.
| Window Type | Common Opening Sizes (WxH, cm) | Usage |
|---|---|---|
| Bathroom window | 60x90, 60x120 | Bathroom |
| Kitchen window | 90x120, 120x120 | Kitchen |
| Bedroom window | 120x150, 150x150 | Bedroom |

| Floor-to-ceiling / balcony door | 180x210, 240x210 | Balcony door, floor-to-ceiling window |
Chinese residential ceilings run high (2.8-3.0 m unfinished, 2.6-2.8 m after renovation), with mostly sliding and casement windows. IKEA China carries the same VECKLARFLY venetians, rollers and TRIPPEVALS honeycombs as elsewhere, but holds a small share; the market stays custom-first across rollers, venetians, honeycombs, zebras and romans.
India: custom-first under CPWD
India's Central Public Works Department (CPWD) set out a doors-and-windows standardization memorandum in 2006 for residential room windows. The market is predominantly custom, with ready-made venetians and rollers virtually absent.
| Window Type | Standard Sizes (WxH, cm) | Usage |
|---|---|---|
| Residential room window | 90x120 | Bedroom, living room (most common) |
| Residential room window | 75x90-135 | Small room |
| Residential room window | 90x60-135 | Auxiliary room |
| Bathroom window | 60x90, 60x120 | Bathroom |
| Kitchen window | 90x120 | Kitchen |
Indian residential ceilings run 2.7-3.0 m, with mostly sliding and casement windows. The market is fully custom for rollers, venetians and honeycombs, is price-sensitive, and custom orders typically carry lower MOQ.
Southeast Asia: custom-first, no shared standard
Southeast Asia spans Singapore, Malaysia, Thailand, Indonesia, Vietnam, the Philippines, Myanmar, Cambodia, Laos and Brunei, each with different building standards and development levels. All are predominantly custom with limited ready-made channels; Malaysia, Thailand and the Philippines have IKEA selling ready-made venetians and rollers.
Indonesia:
| Window Type | Common Sizes (WxH, cm) | Usage |
|---|---|---|
| Bedroom window | 80x120 | Bedroom (most common) |
| Sliding window | 120x150 | Living room, bedroom |
| Casement window | 60x120 | Bathroom, small room |
| Fixed window | 100x200 | Living room, lobby |
| Kitchen window | 50x60-80 | Kitchen |
Indonesian ceilings run 2.8-3.0 m with sliding windows dominant; the market is fully custom.
Vietnam:
| Window Type | Common Sizes (WxH, cm) | Usage |
|---|---|---|
| 2-panel window | 100x120, 110x130, 120x140 | Bedroom, study |
| 3-panel window | 150x140, 160x150, 180x160 | Living room, common area |
| 4-panel window | 211-215x120 | Large living room |
Vietnamese ceilings run relatively high (2.8-3.2 m) with aluminium windows dominant; the market is fully custom.
Singapore, Malaysia, Thailand, the Philippines. Singapore HDB uses standardized prefabricated components, but window sizes vary by project; used aluminium windows on Singapore platforms such as Carousell commonly measure 242x122 cm. Malaysia, Thailand and the Philippines each run different standards with wide size variation. All are predominantly custom, with Malaysia, Thailand and the Philippines carrying IKEA ready-made venetians (VECKLARFLY, 60x155 to 140x155 cm) and rollers (90x190, 100x195 cm), but IKEA holds a small local share. Singapore and Malaysia demand higher custom quality; Thailand and the Philippines are more price-sensitive.
Bottom line
Treat Asia-Pacific as two different businesses. Put ready-made volume into Australia and New Zealand - cover the 60-210 cm wide, 150-240 cm drop grid across aluminium venetian, timber venetian, PVC venetian and blockout/light-filtering roller, and respect AS/NZS certification. Run Japan, Korea, China, India and Southeast Asia as custom-first, hold Japan to the +/-1 mm precision it expects, and watch IKEA-type retail channels for ready-made pull. Yuehua has supplied window blinds since 1998 from BSCI-audited production, and we build the aluminium venetian, roller, honeycomb and roman lines this region buys.
For the other emerging-region comparison, the Latin America size guide runs the same custom-versus-ready-made split. Because Australia/New Zealand demand AS/NZS certification, the Australia blind compliance guide covers the rules behind those windows. On the product side, the aluminium venetian blind is the stocked core of the AU/NZ ready-made venetian range.
