The ¾ size mattress sits between a twin and a full — roughly 48 inches wide by 75 inches long. It's a less common size, but it's genuinely useful in the right situation: tight guest rooms, teen bedrooms, studio apartments, or older homes with custom frames built around this dimension.
This guide covers what the ¾ size actually is, how it compares to other sizes, and which options are worth considering at LA Mattress.
A ¾ size mattress — also called a three-quarter bed or small double — measures approximately 48 inches wide by 75 inches long. The name comes from it being about three-quarters the width of a standard full (54") mattress.
This size was fairly common in American homes built before the 1950s. While it's not a mainstream size today, select mattress manufacturers still produce them, and LA Mattress carries several options across different comfort levels and constructions.
| Size | Width | Length | Best For |
|---|---|---|---|
| Twin | 38" | 75" | Kids, single sleepers in small rooms |
| ¾ (Three-Quarter) | 48" | 75" | Teens, single adults, tight guest rooms |
| Full (Double) | 54" | 75" | Single adults, couples in very tight spaces |
| Queen | 60" | 80" | Couples, most single adults |
| King | 76" | 80" | Couples who want maximum space |
At 48" wide, a ¾ gives a single sleeper 10 more inches than a twin — which makes a real difference if you move around at night. It's still not a comfortable fit for two adults sharing a bed regularly.
| Pros | Cons |
|---|---|
| More width than a twin without a full-size footprint | Not a standard size — fewer bed frames and bedding options |
| Good for space-constrained rooms and apartments | 75" length isn't ideal for tall sleepers |
| Generally more affordable than a full or queen | Limited selection compared to standard sizes |
| Solid option as a transitional bed for teens | Not comfortable long-term for most couples |
| Works well in older homes with custom frames | Specialty bedding can be harder to source |
LA Mattress carries several ¾ size options across different firmness levels and constructions. Here are the best picks currently available:
A firm memory foam mattress with hypoallergenic materials and solid temperature regulation. Good for back and stomach sleepers who want close body contouring without a soft feel.

A premium latex hybrid with a plush feel. Natural latex offers responsive bounce and excellent heat dissipation — a strong choice for hot sleepers who want a softer surface.

A luxury firm option with an advanced coil system and targeted pressure relief in the comfort layers. Well-suited for back pain sufferers who need support without a completely hard feel.
A handcrafted mattress with reinforced edges and high-density foam layers. If long-term durability and craftsmanship matter to you, this is the most premium ¾ size pick available.

The budget-friendly option. The pillow top layer adds softness, and the supportive core handles basic spinal alignment. A solid choice if you're setting up a guest room without a large spend.
A hybrid option with foam and coil layers for a soft, cushioned feel with structural support underneath. Reinforced edges maximize the usable sleeping area on this already-compact size.

Standard dimensions are 48 inches wide by 75 inches long. Always confirm with the specific manufacturer, as slight variations exist.
No. A full (double) mattress is 54 inches wide. A ¾ size is 48 inches wide — 6 inches narrower. Both are typically 75 inches long.
Technically yes, but it's tight. Two adults sharing a ¾ mattress each get roughly 24 inches of space — less than a single twin provides one person. Most couples are more comfortable on a queen or larger.
Specialty bedding in ¾ size is available from some online retailers. As a workaround, some people use deep-pocket twin XL fitted sheets, though the fit won't be exact.
Yes — it's one of the best use cases for this size. It gives a growing teen more room than a twin without requiring the full footprint of a full or queen bed.
Same guidance as any mattress: side sleepers generally do well with medium to plush, back sleepers with medium to firm, and stomach sleepers typically need a firm core. Not sure? Visit our mattress types page or ask a sleep expert at any LA Mattress showroom.
