Duvet, Sheet & Towel Size Guide: CM to Inches, Explained
Shopping for bedding and towels gets confusing fast when sizes are listed in centimeters on one page and inches on the next. If you've ever stared at a "200 x 200 cm" duvet cover and wondered whether it fits your queen bed, you're not alone — it's one of the most common questions shoppers have before they buy. This guide breaks down duvet, sheet, and towel sizing in both measurement systems, so you can shop with confidence instead of guessing.
Quick answer: most standard queen duvet covers fall between 88–92 inches (224–234 cm) wide, most twin sheets are sized for a 38 x 75 inch (96.5 x 190.5 cm) mattress, and towel softness comes down to GSM (grams per square meter) — 700 GSM sits in the plush, hotel-quality range. Read on for the full breakdown.
Duvet & Comforter Size Chart (US + EU/Metric)
A duvet cover needs to run a little larger than your comforter or duvet insert so it slides on easily and drapes properly over the sides of the bed. Sizing conventions differ between the US and Europe, which is why the same bed size can show up with two very different-looking numbers.
US duvet cover sizes:
| Bed size | Inches | Centimeters |
|---|---|---|
| Twin / Twin XL | 68 x 90 in | 173 x 229 cm |
| Full / Double | 79 x 90 in | 201 x 229 cm |
| Queen | 88 x 92 in | 224 x 234 cm |
| King | 104 x 90 in | 264 x 229 cm |
| California King | 104 x 98 in | 264 x 249 cm |
EU / Metric duvet cover sizes:
| Bed size | Centimeters | Inches |
|---|---|---|
| Single | 140 x 200 cm | 55 x 79 in |
| Double / Full | 200 x 200 cm | 79 x 79 in |
| Queen (metric) | 200 x 220 cm | 79 x 87 in |
| King (metric) | 220 x 240 cm | 87 x 94 in |
If you're comparing a 180 x 200 cm duvet — a size commonly used for a full or queen bed in European sizing — that converts to roughly 70.9 x 78.7 inches. It will sit closer to a US full-size fit than a queen, so measure your mattress before assuming it's a direct swap.
Rule of thumb: always size your duvet cover up from your mattress dimensions, not to match them exactly. A cover that's the same size as your bed will look tight and expose the sides of your comforter.
Sheet Size Chart in CM and Inches
Sheets are sized to the mattress itself, not with the extra allowance duvet covers need. Here's how standard US mattress sizes translate to centimeters.
| Mattress size | Inches | Centimeters |
|---|---|---|
| Twin | 38 x 75 in | 96.5 x 190.5 cm |
| Twin XL | 38 x 80 in | 96.5 x 203 cm |
| Full / Double | 54 x 75 in | 137 x 190.5 cm |
| Queen | 60 x 80 in | 152 x 203 cm |
| King | 76 x 80 in | 193 x 203 cm |
| California King | 72 x 84 in | 183 x 213 cm |
A twin sheet set sized for 96.5 x 190.5 cm is what to look for if you're shopping with a metric tape measure. Fitted sheets also need enough pocket depth to wrap around your mattress — most modern mattresses run 12–16 inches (30–41 cm) deep, so check the fitted sheet's pocket depth against your actual mattress height, especially if you have a pillow-top or memory foam mattress.

What Does GSM Mean? Towel Weight Explained
GSM stands for grams per square meter — it's the standard measurement for how densely woven a fabric is, and for towels, it's the single best indicator of thickness, absorbency, and how plush a towel will feel.
- 300–400 GSM: Lightweight, quick-drying, common in gym or beach towels.
- 400–600 GSM: Everyday bath towels — a good balance of softness and drying time.
- 600–900 GSM: Plush, hotel- and spa-quality towels. Heavier, more absorbent, and slower to dry.
- 900+ GSM: Ultra-dense, luxury weight. Very absorbent but takes noticeably longer to air dry.
Higher GSM isn't automatically "better" for every use case — it depends on whether you want a lightweight everyday towel or a heavier, more indulgent one.
700 GSM Towels — What to Expect
A 700 GSM towel sits firmly in the plush, hotel-quality range. Here's what that weight actually means in daily use:
- Noticeably thick and dense to the touch, with a heavier drape than standard retail towels
- High absorbency — designed to dry you off in fewer passes
- Slower to air-dry than lighter towels, so good ventilation or a slightly longer drying cycle helps maintain the fabric
- Holds up well to repeated washing without going thin, provided it's laundered with a mild detergent and not over-dried on high heat
If you're deciding between a 700 GSM towel and a lighter option, think about how you use it: for a daily-use bathroom towel, 700 GSM delivers a spa-like feel without becoming impractical to launder.
