How Many Square Feet Is an 8x10 Room?
A 8 × 10 ft room is 80 square feet — 7.43 square metres, or 8.89 square yards.
Multiply the two sides together: 8 × 10 = 80. In metric that is 2.44 m × 3.05 m = 7.43 m².

What fits in a 8x10 room
Counted as a plain grid layout in whichever direction packs more in, with no walkways and no diagonal placement — so treat each figure as the floor, not the ceiling.
| Item | Footprint | How many fit | Floor used |
|---|---|---|---|
| King bed | 6.3 × 6.7 ft | 1 | 53% |
| Queen bed | 5 × 6.7 ft | 2 | 83% |
| Full (double) bed | 4.5 × 6.3 ft | 2 | 70% |
| Twin bed | 3.2 × 6.3 ft | 3 | 74% |
| Three-seat sofa | 3.2 × 7 ft | 3 | 83% |
| Dining table (seats 6) | 3 × 6 ft | 3 | 68% |
| Office desk | 2.5 × 5 ft | 6 | 94% |
| Ping-pong table | 5 × 9 ft | 1 | 56% |
| 8×10 area rug | 8 × 10 ft | 1 | 100% |
| Yoga mat | 2 × 5.7 ft | 5 | 71% |
How a 8 × 10 ft room lays out
At 1.3:1 this is the proportion most rooms are actually built to — long enough to give furniture a clear front and back, square enough that neither wall dominates the arrangement.
A queen bed is 6 ft 8 in long, so with its head to an 8 ft wall it leaves 1 ft 4 in — too tight to walk past, which is why a queen in a room this narrow normally runs along the 10 ft wall instead. The 10 ft wall takes a 7 ft three-seat sofa and still leaves 3 ft, enough for a side table and a floor lamp.
A footprint this size and shape is typically a nursery or box room, or a home office — typical ranges rather than a rule, and ballpark rather than sourced, like the figures above (see the methodology page).
Materials for 80 square feet
Quantities include each material's usual waste allowance and round up to whole units, because you cannot buy part of a box.
| Material | Sq ft to buy | Quantity |
|---|---|---|
| Carpet | 88 (+10%) | 8 roll feet |
| Drywall | 88 (+10%) | 3 sheets |
| Flooring (laminate/vinyl) | 88 (+10%) | 5 boxes |
| Hardwood Flooring | 88 (+10%) | 4 boxes |
| Paint | 84 (+5%) | 1 gallon |
| Tile | 88 (+10%) | 6 boxes |
Working with a 8x10 room
A 8 by 10 foot room is 80 square feet of floor, which is 7.43 square metres, 8.89 square yards, or 0.0018 of an acre. The arithmetic is a single multiplication — 8 × 10 — and every other figure on this page follows from it.
The walls are a different number. The perimeter of a 8 × 10 room is 36 feet, so with a standard 8 ft ceiling the four walls come to about 288 square feet before you deduct anything. Take off roughly 21 square feet for each door and 15 for each window: one door and two windows brings it to about 237 square feet, which at 375 square feet to the gallon is 1 gallon of paint per coat, or 2 for the two coats a colour change needs.
For flooring or tile, add the waste factor before you order rather than after. At the usual 10% allowance a 80 square foot floor needs 88 square feet of material bought, and a diagonal or herringbone lay pushes that to 92. The table above rounds each material up to whole boxes and sheets, because that is the smallest unit anyone will sell you.

Frequently asked questions
How many square feet is a 8x10 room?
A 8 by 10 foot room is 80 square feet. Multiply the two sides together — 8 × 10 — and that is the floor area. The same figure is shown above in square metres, square yards and acres, along with a to-scale drawing and the quantity of each material a room this size needs.
What can fit in a room this size?
The table above counts how many of each item fit as a plain grid, laid whichever way round packs more in, with no walkways and no diagonal placement. Treat every figure as a floor rather than a ceiling: it tells you the room is physically large enough, not that the layout would be comfortable. A usable room generally needs 30 to 36 inches of clearance on at least one side of each piece of furniture.
Is this the floor area or the wall area?
The floor area. Wall area is a different calculation: multiply each wall's width by the ceiling height and add them together, then subtract the doors and windows. For a 8 by 10 room with an 8 ft ceiling, the four walls come to about (8 + 10) × 2 × 8 square feet before any deductions.
