Square Feet to Linear Feet the width is the missing piece
Enter your area and the width of the material. Works in imperial (ft², inches, linear feet) and metric (m², centimetres, running metres).
One Formula
Area Alone Is Not Enough
How do you convert square feet to linear feet?
At a Glance
Divide the area by the material width, with both expressed in the same unit: linear feet = square feet ÷ (width in inches ÷ 12). 500 ft² of 5-inch-wide flooring needs 1,200 linear feet. The same 500 ft² in 7-inch boards needs only 857 linear feet — wider material means fewer running feet.
A square foot measures area — two dimensions. A linear foot measures length — one. You cannot get from one to the other without knowing the second dimension, and for boards, planks, rolls and trim that second dimension is the width.
That is why the question has no universal answer. A square foot of 3-inch trim is 4 linear feet; a square foot of 12-inch board is 1 linear foot. Same area, four times the length.
| Material width | Linear feet per ft² | Linear feet for 500 ft² |
|---|---|---|
| 3 in | 4.00 | 2,000 |
| 5 in | 2.40 | 1,200 |
| 7 in | 1.71 | 857 |
| 12 in | 1.00 | 500 |
linear length = area × (width units per length unit) ÷ widthThese are the values the calculator loads by default.
Start with the area
500 ft² — the room you are covering, including any waste allowance you want to carry.
Put both measurements in the same unit
The width is in inches and the answer is in feet, so scale the area: 500 × 12 = 6,000.
Divide by the width
6,000 ÷ 5 = 1,200 linear feet.
Check against wider material
Switch the width to 7 inches and the same room needs only 857 linear feet. Wider boards mean fewer running feet — but not less area, and usually not less money.
The linear figure is what suppliers who sell by the running foot or metre need — trim, moulding, worktops, fabric, fencing boards. It is not a quantity of material in any other sense: 1,200 linear feet of 5-inch flooring and 857 linear feet of 7-inch flooring cover exactly the same floor.
Two things this figure does not include:
Waste. Cuts at the ends of rows, damaged pieces and pattern matching typically add 5-10 % for a straight lay and up to 15 % for a diagonal one. Add it to the area before converting, not after.
Packaging. Material is sold in boxes or bundles of fixed length, so round up to whole packs. Our Flooring Calculator handles the pack maths; Square Footage Calculator gets you the area in the first place if you only have room dimensions.
This assumes full-width coverage with no offcuts
The formula treats your area as if it could be tiled with continuous strips of exactly the stated width and no waste. Real installations lose material at every wall, around every obstacle, and to the offcut at the end of each row that is too short to start the next one.
Check whether the stated width is the face width (what you see once installed) or the overall width including a tongue. For tongue-and-groove material those differ by a few millimetres, and over a large floor the difference compounds. Manufacturers usually quote coverage per pack — use that as the cross-check.
