# What are the dimensions of the L-shaped corner floor sofa?

*One number on a listing is often a single cushion. The whole L is larger. Here are both, side by side.*

Also asked as: Is it 98½ in (250 cm) wide or 300?; How long is the couch from arm to arm?

> **The quick answer:** The standard L-shaped corner floor sofa measures 118 in (300 cm) on the long side and about 79 in (200 cm) on the short side, wall to wall, and 14 in (35 cm) high. It is two 39 x 79 in (100 x 200 cm) sofas joined at the corner. A listing figure around 76-79 in usually describes one base cushion, not the whole sofa.

## One cushion is not the sofa

The most common mix-up is a small one. A listing says 76 or 79 in, and you picture the whole sofa. That figure is often one base cushion.

The corner L is two 39 x 79 in (100 x 200 cm) sofas joined at the corner. Wall to wall, that is 118 in (300 cm) on the long side and about 79 in (200 cm) on the short side. The seat sits 14 in (35 cm) off the floor.

Each seat cushion is 78 x 39 in, so the pieces can move later. All sizes can be customized. The [modular floor sofa layouts](https://cushionguide.com/guides/modular-floor-sofa-layouts/) Pattern shows arrangements, and the [floor sofa buying guide](https://cushionguide.com/guides/floor-sofa-buying-guide-height-space/) covers space. The [modular floor sofas](https://cushionguide.com/cushions/modular-floor-sofas/) atlas holds the rest.

Which wall in your room is the long one?

A cushion is a number.
A sofa is several.
Ask which one you are reading.

## Check the L against your walls

1. **Measure the long wall**: Tape from the corner to where the sofa should end. The standard L needs 118 in (300 cm).
2. **Measure the short wall**: From the same corner. The L needs about 79 in (200 cm).
3. **Check the depth**: Each seat is 39 in (100 cm) deep. Leave a hand's width of floor where you walk.
4. **Read the listing number twice**: If it says 76-79 in, ask: one cushion, or the whole sofa?

> **Tailor's margin:** An L-shaped floor sofa listed at 79 in is often one base cushion; the full L runs 118 in (300 cm) on the long wall.

> Two 39 x 79 in floor sofas joined at the corner make an L of 118 in on the long wall and 79 in on the short.

## Buyer questions

**A common question:** What are the dimensions of your L-shaped corner sofas?

**The workshop's answer:** The corner L is two 39 x 79 in (100 x 200 cm) sofas joined: 118 in (300 cm) on the long side and 79 in (200 cm) on the short side, wall to wall. The 39 x 79 in modular sofa opens into a 79 x 79 in (200 x 200 cm) bed, and the corner sofa with ottoman is 79 x 118 in (200 x 300 cm). All can be customized.

**A common question:** The L-shaped sofa lists 78 inches and 118 inches. How long is each side?

**The workshop's answer:** Those numbers are the L's overall footprint: 118 in on the long side and about 79 in on the short side. Each floor seating cushion is 78 x 39 in, so you can reconfigure them.

**A common question:** How big is the open corner couch once all the pieces are together?

**The workshop's answer:** The listing figure was for one base cushion. With every piece combined it is 118 x 79 x 14 in (300 x 200 x 35 cm), built on the same core cushions as the corduroy modular sofa.

**A common question:** What does the corduroy modular corner sofa measure?

**The workshop's answer:** About 78.7 x 78.7 in (200 x 200 cm), with 2 seat cushions, 2 L-shaped backrests and 1 straight backrest; an ottoman can be added. Opened out into a rectangle without the ottoman, it measures 79 x 118 in (200 x 300 cm).

## Questions buyers ask next

### Can the corner L be laid out as a bed?

Yes. Take off the loose backrests and lay the seat cushions flat side by side. The pieces arrange as 118 x 39 in (300 x 100 cm) or 79 x 79 in (200 x 200 cm); it doesn't fold like a traditional sofa bed.

### Can one side of the L be shorter than standard?

Sizes can be customized. Give the wall-to-wall length you want on each side and the depth you need; the standard L is 118 in by about 79 in (300 x 200 cm).

### How deep is each seat in the corner L?

Each sofa in the L is 39 in (100 cm) deep, and each seat cushion measures 78 x 39 in. Keep the walkway clear where the two depths meet.
