How do I measure blinds for inside mount versus outside mount?

For inside mount, measure the recess width at the top, middle and bottom and quote the smallest; measure the height at the left, center and right and quote the largest. The factory then deducts a small clearance automatically. For outside mount, add coverage on each side of the frame; outside-mount windows have no stock sizes and are quoted as custom. Always confirm the mount method before any sizing quote.

What is the difference between ready-made and custom blind sizes for buyers?

Ready-made (stock) blinds cover standard residential window sizes and carry a lower MOQ per run. Custom blinds are cut to the customer's exact opening and normally carry a higher MOQ, a longer lead time, and possible oversize or splicing surcharges. Stock the mainstream combos first; route older renovations, out-of-square openings and extra-large windows to custom.

How do I turn a customer's window measurements into stock blind sizes?

Match the measured opening to the nearest ready-made width and height in the supplier's stock grid rather than rounding up blindly. If the opening does not fall on a stock size, or the recess depth is too shallow for inside mount, the window goes custom instead. State the measurement tolerance and any oversize or splicing surcharges on the quote so the buyer can price it back to their own customer.

Can you customize sizes, colors, and packaging?

Yes, we offer full customization including: custom sizes, custom fabric colors based on Pantone or sample, custom printing patterns, color-matched components, branded components with your logo, custom packaging (PP bags, shrink wrap, PET clear boxes, paper boxes), custom printed color cartons, hang tags, and private label with your brand name and instruction manuals.

What are the main differences in window blind size standards across markets?

North America primarily uses imperial units (inches) with standard widths ranging from 20" to 72" and standard drops from 48" to 84". Europe uses metric units with common widths of 60–180 cm and drops of 130–250 cm. Latin America varies by country — some use imperial, some metric, and many have less standardized sizing due to diverse construction practices. Asia-Pacific includes both mature standard-size markets (Australia, New Zealand) and markets with higher customization rates.

Latin America Window Blind Ready-Made Sizes: B2B Sourcing Guide

Published 2026-08-27 · Last updated 2026-10-19 · By Yuehua Editorial · 13 min read · 123 views

Latin America is the hardest size region to stock for, because there is no cross-national building code and every country mixes US, European and local traditions. The single most important split is by unit: South America (Brazil, Argentina, Chile, Colombia, Peru and the Andes) is pure metric, while Mexico, Central America and the Caribbean run inches and centimeters together in the same retail channel. Heights then follow ceiling height - Brazil and Chile sit high (2.8-3.0 m) and need tall stock, Mexico and Argentina lower (2.5-2.7 m). The tables below are the ready-made grids we quote against; sizing data in this guide reflects current ready-made programs as of October 2026.

Key takeaways

Split the region by unit, not by continent: label South American product in centimeters only, but Mexico, Central America and the Caribbean need centimeter and inch labels together on packaging and manuals.
In imperial-influenced countries the best sellers are metric conversions of imperial integers - 48 in ~ 122 cm, 72 in ~ 183 cm, 84 in ~ 213 cm, 96 in ~ 244 cm - not round metric numbers like 120/180 cm.
Heights follow ceilings: Brazil and Chile mainstream 220-240 cm stock (Brazil 220 cm, Chile 240 cm), while Argentina runs only two height tiers, 190 cm and 250 cm.
Brazil and Mexico are the two large, mature ready-made markets; Central America, Venezuela and the smaller Andean countries are custom-heavy, so keep ready-made inventory there to rollers and zebras in a few universal sizes.

Why sizing fragments across Latin America

Six forces pull the region apart:

No unified building code. Mexico leans on US codes; Brazil runs its own NBR system; Argentina uses IRAM; Chile uses NCh - each country operates alone.
Metric and imperial coexist. Mexico, Central America and the Caribbean sell both inches/feet and centimeters; Brazil, Argentina, Chile and Colombia are uniformly metric.
Ceiling height sets blind height. Brazil and Chile ceilings run 2.8-3.0 m, with ready-made heights commonly 220-240 cm; Mexico and Argentina sit lower at 2.5-2.7 m, with ready-made heights 180-200 cm.
Climate shapes the window. Northern Mexico and northern Chile are hot and dry with smaller windows; northern Brazil's tropical zone uses larger windows for ventilation; Andean highlands have big day-night swings and smaller windows.
Uneven retail maturity. Brazil, Mexico, Chile and Argentina have mature ready-made channels; Central America and the smaller Andean countries skew custom.
Unit inconsistency is unique here. South America (Brazil, Argentina, Chile, Colombia, Peru, Ecuador, Bolivia, Paraguay, Uruguay) is metric in practice as well as on paper. Mexico, Central America (Panama, Costa Rica, Guatemala, Honduras, El Salvador, Nicaragua) and Caribbean states (Dominican Republic, Cuba and others) are officially metric but build and retail in both units, because US-imported aluminum profiles, hardware and lumber arrive in inches and large chains label in imperial. Panama is the most imperial-influenced, with the US dollar as legal tender and 110V/60Hz US-standard electricity. Guatemala even uses both the US pound and the traditional Spanish libra (460 g), and gasoline is sold by the gallon.

The buying rule is simple: do not supply one Latin American size list. Build Brazil and Mexico separately, label Mexico/Central America/Caribbean in both units, and keep South America metric-only.

Mexico: metric primary, imperial parallel

Mexico is Latin America's second-largest economy. US influence runs deep in its building codes, and retail sells imperial and metric at the same time. Officially metric, in practice American-imported aluminum and hardware arrive in inches, chains label both units, and border projects for US clients go imperial only.

Window Type	Common Sizes (WxH, cm)	Usage
Bathroom/Small	60x60, 60x90	Bathroom, laundry room
Kitchen	80x100, 100x100, 120x100	Kitchen (above countertop)
Bedroom	100x120, 120x120, 120x150	Bedroom, study
Living Room	150x120, 150x150, 180x150	Living room, master bedroom
Floor-to-Ceiling/Patio Door	180x210, 200x240	Balcony door, floor-to-ceiling window

Imperial reference: large chains also label in inches - 24x24", 36x48", 48x48", 48x60", 60x48", 60x60", 72x84" and so on. 120x120 cm (about 48x48") is the most common standard bedroom window size in Mexico.

Common ready-made blind sizes in Mexico:

Category	Common Widths (cm)	Common Heights (cm)	Best-Selling Combinations
Roller Blinds	60, 80, 100, 120, 140, 150, 180, 220	120, 150, 180, 200, 220	120x180, 150x180, 120x220
Zebra Blinds	80, 100, 120, 150	120, 150, 180, 200, 220	120x180, 150x220
Aluminum Venetian	60, 80, 100, 120	100, 120, 150, 180	60x120, 80x150, 100x120
Cellular/Honeycomb	60, 80, 100, 120	100, 120, 150, 180	60x120, 80x150

Imperial reference: international brands in Mexico label rollers as 122x155 cm and 122x195 cm (imperial 48x61" and 48x77" conversions); local brands label both units. The 220 cm (about 84") height is a distinctive Mexican spec for taller living-room windows.

Brazil: pure metric, tall stock

Brazil is the region's largest economy and blind market. It is uniformly metric, and residential ceilings run high (2.8-3.0 m), which pushes ready-made blind heights up.

Room Type	Standard Size (WxH, cm)	Recommended Window Type
Bedroom (Quarto)	120x100	2-panel sliding or maxim-ar
Living Room (Sala)	150x120	4-panel sliding
Kitchen (Cozinha)	120x100	Maxim-ar (ventilation even when raining)
Bathroom (Banheiro)	60x60	Maxim-ar or top-hung
Service Area (Area de servico)	100x100	2-panel sliding

Brazil has performance standards such as NBR 15575, but no mandatory rule for specific window dimensions; the sizes above are what the market actually builds. Brazilian windows are generally wider than they are tall, because ceilings are high but sills are higher too.

Common ready-made blind sizes in Brazil:

Category	Common Widths (cm)	Common Heights (cm)	Best-Selling Combinations
Roller Blinds	100, 120, 140, 150, 160, 200	140, 160, 180, 220, 235	140x160, 160x220, 120x220
Zebra Blinds (Double Vision)	100, 120, 150	140, 160, 180, 220	150x140, 120x160
Aluminum Venetian	60, 80, 100, 120	100, 120, 140, 160	80x120, 100x140
Cellular/Honeycomb	60, 80, 100, 120	100, 120, 140, 160	80x120, 100x140

The 220 cm height is the mainstream ready-made roller height in Brazil (matching high ceilings), with 160x220 cm and 120x220 cm the best sellers. Ready-made roller widths commonly run 120/140/160 cm, and sunscreen fabric ready-made widths can exceed 200 cm.

Argentina: pure metric, two height tiers

Argentina is South America's third-largest economy, uniformly metric with a mature ready-made market. Roller widths stepping up in 15 cm increments are an industry convention.

Room Type	Common Sizes (WxH, cm)
Bathroom (Bano)	40x60, 50x50, 60x60
Kitchen (Cocina)	80x100, 100x120
Bedroom (Dormitorio)	120x120, 120x100
Living Room (Living)	150x120, 150x150

Common ready-made blind sizes in Argentina:

Category	Common Widths (cm)	Common Heights (cm)	Best-Selling Combinations
Roller Blinds	75, 90, 105, 120, 135, 150, 165, 180, 200	190, 250	120x190, 150x190, 120x250
Zebra Blinds	90, 105, 120, 135, 150	190, 250	120x190, 150x250
Aluminum Venetian	60, 80, 100, 120	100, 120, 150, 190	80x120, 100x150
Cellular/Honeycomb	60, 80, 100, 120	100, 120, 150, 190	80x120, 100x150

Argentine ready-made rollers step in 15 cm widths (75/90/105/120/135/150/165/180/200 cm) but stock only two heights: 190 cm for standard ceilings and 250 cm for higher ceilings or floor-to-ceiling windows.

Chile: pure metric, 240 cm mainstream

Chile is one of South America's more developed markets, with high residential ceilings (2.8-3.0 m) that push ready-made blind heights up; 240 cm is the mainstream.

Room Type	Common Sizes (WxH, cm)
Bathroom	60x60, 60x90
Kitchen	80x100, 100x120
Bedroom	100x120, 120x150
Living Room	150x150, 180x180, 200x200

Common ready-made blind sizes in Chile:

Category	Common Widths (cm)	Common Heights (cm)	Best-Selling Combinations
Roller Blinds	90, 120, 130, 140, 150	120, 180, 200, 240	120x180, 130x240, 140x240
Zebra Blinds (Duo)	90, 120, 150	180, 200, 250	90x250, 120x200
Aluminum Venetian	60, 80, 100, 120	100, 120, 150, 180	80x120, 100x150
Bamboo Roller Blinds	90, 120, 150	120, 180, 200	90x120, 120x180, 150x200

The 240 cm height is the Chilean ready-made roller mainstream (130x240 cm and 140x240 cm best sellers), driven by high ceilings. Bamboo rollers have strong acceptance in Chile and are a distinctive category here.

Central America, the Caribbean and the Andes

Central America (Panama, Costa Rica, Guatemala, Honduras, El Salvador, Nicaragua), the Caribbean (Venezuela, Dominican Republic, Cuba and others) and the Andes (Colombia, Peru, Ecuador, Bolivia, Paraguay, Uruguay) sit below Brazil, Mexico, Chile and Argentina in retail maturity and building standardization. Their ready-made markets are thinner and skew custom.

Panama and Central America: high imperial use

Panama is one of Central America's more developed markets, deeply US-influenced (US dollar as legal tender, 110V/60Hz US-standard power), and is the most imperial-influenced country in the region. Local blind shops run mostly custom - zebras, sunscreen rollers, blackout rollers - with limited ready-made stock. Costa Rica, Guatemala, Honduras, El Salvador and Nicaragua sit lower on development and standardization, window sizes vary widely, the ready-made market is tiny, and custom dominates; shops mostly offer custom venetians (slats 2.5" to 4.5", 3.5" most common) and custom rollers.

Common ready-made blind sizes in Central America:

Category	Standard Widths (cm)	Standard Heights (cm)	Best-Selling Combinations
Roller Blinds	60, 90, 100, 120, 150, 180, 200	120, 150, 180, 220	100x180, 120x220, 120x180
Zebra Blinds	80, 100, 120, 150	150, 180, 200, 220	100x180, 120x200
Aluminum Venetian	60, 80, 100, 120	100, 120, 150	60x120, 80x150
Cellular/Honeycomb	60, 80, 100, 120	100, 120, 150	60x120, 80x120

Imperial reference: construction and retail commonly use inches - 24x48", 36x60", 48x72", 60x84", 72x96" and so on. Panama leads on imperial use, with 240 cm (about 96") heights for floor-to-ceiling windows and balcony doors. Label packaging and manuals in both centimeters and inches. Because the ready-made market is thin, B2B supply here should lean custom; if you do stock ready-made, lead with rollers in universal 60/90/120/150 cm widths and 120/150/180/220 cm heights.

Venezuela and the Caribbean: metric primary, imperial parallel

Venezuela is US-influenced with Americanized codes and both units in use, but economic instability has shrunk the ready-made market and pushed custom share very high. Local retailers' common ready-made rollers are 180x150 cm, 120x180 cm and 140x180 cm. The Dominican Republic, Cuba, Jamaica and the rest of the Caribbean similarly skew custom with small ready-made markets and common imperial use; supply them custom-first and do not hold large ready-made stock.

Common ready-made blind sizes in Venezuela:

Category	Common Widths (cm)	Common Heights (cm)	Best-Selling Combinations
Roller Blinds	100, 120, 140, 150, 180	150, 180, 200	120x180, 140x180, 180x150
Zebra Blinds	100, 120, 150	150, 180, 200	120x180, 150x200
Aluminum Venetian	60, 80, 100, 120	100, 120, 150	80x120, 100x150

Imperial reference: common imperial equivalents include 40x60", 48x72", 56x72" and 72x60"; the Dominican Republic, Cuba and the rest of the Caribbean also commonly use imperial.

Colombia, Peru and the other Andes: pure metric

Colombia, Peru, Ecuador, Bolivia, Paraguay and Uruguay are uniformly metric, with thinner ready-made markets and high custom share. Peruvian home-improvement stores put the mainstream ready-made roller range at 140-159 cm wide and 180-199 cm high. Colombia, Ecuador, Bolivia, Paraguay and Uruguay lack systematic ready-made channel data; Uruguay is more developed and Argentina-influenced, with spec close to Argentina (15 cm roller width steps, heights 190/250 cm).

Common ready-made blind sizes in these countries:

Category	Common Widths (cm)	Common Heights (cm)	Best-Selling Combinations
Roller Blinds	80, 100, 120, 140, 150	120, 150, 180, 200	100x180, 120x180, 140x200
Zebra Blinds	80, 100, 120, 150	150, 180, 200	100x180, 120x200
Aluminum Venetian	60, 80, 100, 120	100, 120, 150	60x120, 80x150
Cellular/Honeycomb	60, 80, 100, 120	100, 120, 150	60x120, 80x120

Ready-made selection is limited here; for B2B supply, keep to rollers and zebras and do not spread specs too thin.

Bottom line

Stock Latin America by unit and by ceiling height, not by one regional size sheet. Label South America metric-only; label Mexico, Central America and the Caribbean in both centimeters and inches, and expect imperial-conversion sizes rather than round metric. Hold tall stock for Brazil (220 cm) and Chile (240 cm), run Argentina's 190/250 cm two-tier range, and keep the thinner markets custom-first with a few universal rollers and zebras. Yuehua has supplied window blinds since 1998 from BSCI-audited production, and we build the roller, zebra, aluminium venetian, cellular and bamboo lines these tables cover.

For the other emerging region, the Asia Pacific emerging markets size guide runs the same comparison. Because US influence drives the inch side of this region, the North America size guide explains the four-digit code those imperial-conversion sizes come from. On the product side, the bamboo roll-up shade matches the bamboo roller category that sells well in the Chilean market.
