Taiwan Bed and Fitted Sheet Sizes: What 3.5 尺, 5 尺, and 6 尺 Mean in cm, and How to Choose a Fitted Sheet (床包)
Moving into a dorm, moving house, or just arriving in Taiwan, the easiest thing to get wrong when buying a fitted sheet is the size. Beds in Taiwan are sized in “尺”, and store names like “單人” (single) and “雙人” (double) differ from store to store. This page explains the size conversion with diagrams first, then recommends one Taiwan-made fitted sheet set we found.
How Many cm Is a “尺” on a Taiwan Bed
Taiwan stores usually size mattresses and sheets in “尺” (pronounced chǐ). The first number is the width and the second is the length, for example 3.5×6.2 尺. The common conversion is 1 尺 ≈ 30.3 cm (we did not find an official Taiwan document for this conversion, so we use 30.3 cm below). Store names such as “單人” and “雙人” vary: two listings both called “單人” can be 3 尺 or 3.5 尺, so look at the 尺 number and the cm, not just the name.
| 尺 size (width×length) | About how many cm | Common store names | Seller's listing for our pick |
|---|---|---|---|
| 3×6.2 尺 | about 91×188 | 單人 (single), 小單人 (small single) | No separate 3 尺 size (the title says a 3 尺 bed can use the 3.5 尺 sheet) |
| 3.5×6.2 尺 | about 106×188 | 單人, 單人加大 (large single) | 105×186 cm |
| 5×6.2 尺 | about 152×188 | 雙人 (double), 標準雙人 (standard double) | 150×186 cm |
| 6×6.2 尺 | about 182×188 | 雙人加大 (large double) | 180×186 cm |
| 6×7 尺 | about 182×212 | 雙人特大 (extra-large double) | 180×210 cm |
A fitted sheet has elastic all around, so the size listed by the seller is usually a few cm smaller than the converted mattress size. The elastic stretches to hold the sheet in place. Whether it fits depends on the mattress size you measure and the store's size chart; we did not test it.
Two Common Mismatches: Length and Depth
Two more things often lead to the wrong purchase. One is length: Taiwan mattresses are usually 6.2 尺 (about 188 cm), shorter than the 200 cm common in many countries. The other is depth: the sheet's pocket depth must be greater than the mattress thickness, or the corners will pop off.
- Length — When we searched, Indonesian stores often listed sheets at 90×200, 100×200, or 120×200 cm, and Vietnamese sellers often listed 150×2 m or 180×2 m. On a Taiwan mattress that is 188 cm long, a sheet like that is about 12 cm too long, so the corners sag and wrinkle.
- Depth — Measure the mattress thickness from top to bottom; include any mattress protector or thin topper. The seller of our pick says this sheet fits mattresses up to about 30 cm thick.
- Width — A 3 尺 bed (about 91 cm) with a 3.5 尺 sheet (listed at 105 cm) has about 14 cm extra width; the elastic pulls it in, but it may be a little loose.

Before You Order, Check These
- Measure the width, length, and thickness of the mattress itself (not the bed frame), then compare with the store's size chart.
- Look at the 尺 number and the cm, not just names like “單人” or “雙人”.
- A 200 cm sheet brought from home or bought elsewhere will be about 12 cm too long on a 188 cm Taiwan mattress.
- If the mattress plus protector is thicker than about 30 cm, this sheet may not fit; ask the seller first.
- A 3 尺 bed with a 3.5 尺 sheet will be a little loose; if that bothers you, look for a sheet listed as 3 尺.
- Choose the pattern in the order note after checkout; wash as the seller says (no tumble drying, no bleach). Warranty and returns follow the store page; save a screenshot before ordering.
Quick Checklist Before Buying
- How wide is the mattress? → about 91 cm = 3 尺, about 106 = 3.5 尺, about 152 = 5 尺, about 182 = 6 尺
- How long is it? → about 188 cm = 6.2 尺, about 212 = 7 尺
- How thick is it? → the sheet's pocket depth must be greater
- Do the name and the cm match? → go by the cm
- How do returns work? → follow the store page
Frequently Asked Questions
- How many cm is a 3.5 尺 bed in Taiwan?
- Using the common conversion of 1 尺 ≈ 30.3 cm, 3.5 尺 is about 106 cm wide and 6.2 尺 is about 188 cm long. The seller lists the 3.5 尺 sheet of our pick at 105×186 cm, with elastic to hold the mattress.
- Can I use a 200 cm sheet from home on a Taiwan bed?
- Taiwan mattresses are usually 6.2 尺 long (about 188 cm), so a 200 cm sheet is about 12 cm too long and the corners tend to sag and wrinkle; the width must match too. We did not test it, so judge for yourself whether it is good enough.
- How big are dorm beds in Taiwan?
- It varies by school and dorm, and we did not find a uniform rule. Measure the mattress width, length, and thickness with a tape measure first. If it is about 91 cm wide, it is 3 尺: look for a sheet listed as 3 尺, or use a 3.5 尺 one (about 14 cm wider).
- What is the difference between a fitted sheet (床包) and a flat sheet (床單)?
- A fitted sheet has elastic all around and wraps the mattress like a cover, so it must match the mattress thickness. A flat sheet is one large piece of fabric laid on top with the edges tucked under the mattress, so it must be larger than the mattress.
- What are the 尺 sizes for Queen and King beds in Taiwan?
- Names vary by store. Some stores call 6×6.2 尺 Queen and 6×7 尺 King, but these measurements do not correspond to US bed sizes. The measurements in cm listed by the store are the most reliable.
- Does this store have a minimum order amount?
- We checked the product page and the store home page and did not see a minimum order amount. The latest rules follow the store page.
What We Found and Did Not Find
What we found: the seller information on our pick's product page and the store home page (November 15, 2026), and the sheet sizes listed by Indonesian stores and Vietnamese sellers that we saw when searching Google in Indonesian and Vietnamese on the same day (mostly 200 cm long). What we did not find: a Taiwan national standard for mattress or sheet sizes, an official Taiwan document for converting 尺 (the conversion above uses the common figure of 1 尺 ≈ 30.3 cm), a uniform rule for dorm beds, verification of the BSMI number the seller lists, the velvet's fiber content, warranty and return window, or a hands-on fitting test.
