A small double mattress size is 4 foot wide and 6 foot 3 inches long which is W120cm x L190cm. If your bedroom is small, a small double mattress can help make the most of the available space and not be imposing in the room.
A small double mattress is big enough for two people sharing, but you may find it a little snug. Ideally, a mattress should be wide enough for you and your partner to lie side by side, hands behind your head, without elbows touching. Small double mattresses are popular for the guest room and for teenagers who want a bit more space to stretch out. Read our mattress size tips here.
A small double mattress is the same length as a double mattress but is narrower by 15cm. Both a double and small double mattress are 6 foot 3 inches long, or 190cm.
