Quilt vs Coverlet: Which Extra Layer to Buy
A quilt is three layers and real warmth at 200–400 GSM. A coverlet is a thinner decorative layer at 150–250 GSM. Neither replaces a 13.5 tog insert in January.

Construction, not the shop heading
Quilt: top, batting (cotton, wool, or poly, often 150–250 g/m² of fill), backing, stitched through. It has loft you can pinch. Coverlet: a single decorative cloth, maybe a light fill, often matelassé or a tight jacquard, made to sit on top and hang. Bedspread is the older, larger cousin that goes to the floor.
GSM on the finished object is the useful number. A 180 GSM coverlet is a tablecloth for a bed. A 350 GSM cotton quilt can replace a 4.5 tog on a 20C night.
| Quilt | Coverlet | |
|---|---|---|
| Layers | 3 (top, batting, back) | 1–2, often no real batting |
| Finished GSM | 200–400 typical | 150–250 typical |
| Warmth | Summer duvet / extra winter layer | Visual, a little warmth |
| Wash | 40C if cotton; check wool batting | Usually easier; still skip softener |
| Overhang | 20–30 cm a side | Often designed to hang lower |
How to use them with a duvet
Summer: quilt only, or coverlet over a 4.5 tog — see summer tog and all-seasons. Winter: duvet at 10.5–13.5, coverlet folded at the foot if you want the look without the heat. Matching the cover to percale or sateen sheets is aesthetics; matching tog to the room is sleep.
Size is overhang, not mattress label
Measure mattress width + 2 × drop. A 150 cm wide mattress with 30 cm drop wants about 210 cm. A “queen quilt” that is 200 × 200 cm will look skimpy. Weight lives in insert vs comforter weight if you are comparing fill; a quilt is not a comforter unless it is sewn as one and used as one.
Questions, answered
- Can a quilt replace a duvet year-round?
- In a warm climate or a hot sleeper’s 18C bedroom, a 350–400 GSM cotton or wool quilt can. In a cold house, no.
- Is matelassé a quilt?
- Usually a coverlet weave that mimics quilting without the batting. Pinch it. If there is no loft, it is a coverlet.
- Wool batting vs cotton?
- Wool loft and humidity handling; cotton is easier to wash at 40C. Polyester batting is the cheap loft that pills inside the channels.
