How Much Material for a 10x12 Bedroom? (2026 Full List)
How much material for a 10x12 bedroom? With 8-ft ceilings, plan on about 2–3 gal of wall paint, 15 sq yd of carpet, 44 ft of baseboard and 1 gal of ceiling paint.
How much wall paint for a 10x12 bedroom?
Assume an 8-ft ceiling. The walls run the room's perimeter — 2 × (10 + 12) = 44 ft — and at 8 ft tall that's 44 × 8 = 352 sq ft of wall area. Subtract the openings, about 21 sq ft for a standard door and 12 sq ft for a typical window, and you're painting about 319 sq ft.
Paint it twice: 319 × 2 ≈ 638 sq ft of coverage. A gallon covers roughly 350 sq ft per coat, so 638 ÷ 350 ≈ 1.8 gal — buy 2–3 gal. Two gallons cover a light color on smooth walls; step up to 3 when you're cutting in a deep shade or want leftover for touch-ups. Let the paint calculator total your walls for you.
How much carpet for a 10x12 bedroom?
The floor is 10 × 12 = 120 sq ft, and carpet is sold by the square yard. Add about 10% for seams, waste and the way rolls are cut: 120 × 1.1 ≈ 132 sq ft, then divide by 9 — 132 ÷ 9 ≈ 14.7 sq yd. Order about 15 sq yd of carpet and have the installer measure for the final cut list; order padding by the same square yards. The carpet calculator converts any room into yards in seconds.
How much baseboard for a 10x12 bedroom?
Baseboard runs along every wall that has one — in a plain rectangular room, the perimeter minus the door opening: 44 − 3 = 41 ft of trim. Add about 10% for cutting ends and miter mistakes: 41 × 1.1 ≈ 45 ft. Trim usually comes in 8-ft sticks, and 45 ÷ 8 ≈ 5.6, so buy 6 sticks (48 ft). The baseboard calculator tallies the linear feet for any doorway count.
How much ceiling paint and drywall for a 10x12 bedroom?
The ceiling mirrors the floor: 120 sq ft. One gallon covers 350–400 sq ft per coat, so even rolling two coats on this ceiling stays inside a single can — order 1 gal of ceiling paint.
If the ceiling is being redone in drywall, sheets are 4×8 ft = 32 sq ft: 120 ÷ 32 = 3.75, so plan on 4 sheets. Add one extra only if the existing framing forces awkward cuts.
Full material list for a 10x12 bedroom
Here's the complete order list — every estimate above in one table:
| Item | How much you need | Order | Tool |
|---|---|---|---|
| Wall paint (two coats) | 319 sq ft of wall ≈ 1.8 gal | 2–3 gal | Paint |
| Ceiling paint | 120 sq ft ceiling | 1 gal | Paint |
| Ceiling drywall (if redoing) | 120 ÷ 32 ≈ 3.75 sheets | 4 sheets (4×8 ft) | — |
| Carpet | 120 + 10% ≈ 132 sq ft | ≈15 sq yd (pad: same) | Carpet |
| Baseboard | 41 ft of trim, ≈45 ft with waste | 6 sticks × 8 ft | Baseboard |
The math assumes an 8-ft ceiling and standard door and window sizes — measure yours and adjust before you order.
Buying and painting tips for a 10x12 bedroom
- Paint from the top down — roll the 120 sq ft ceiling first with its 1 gal, then the walls, then the trim. Ceiling drips land on bare drywall instead of fresh paint, and you can roll walls right up to the ceiling line.
- Buy it all in one batch — same paint line and batch for every gallon, one carpet dye lot, and baseboard from the same rack; a later top-up trip risks color and grain differences that show on a single wall.
- Carry it in one trip — 3 cans of paint, 6 baseboard sticks, 4 drywall sheets and the carpet roll move together, so you wait once for acclimation, pay one delivery fee and never make a last-minute reorder run.

FAQ
How many gallons of paint do I need for a 10x12 bedroom?
About 2–3 gallons for the walls. After subtracting a 21 sq ft door and a 12 sq ft window, the room has about 319 sq ft of wall; two coats are roughly 638 sq ft, and at about 350 sq ft per gallon that's about 1.8 gal — buy 2, or 3 for a deep color. The ceiling takes a separate 1-gal can.
How many square yards of carpet do I need for a 10x12 bedroom?
About 15 sq yd. The 120 sq ft floor plus 10% for waste and seams is about 132 sq ft; divide by 9 and you get roughly 14.7, so round up to about 15 sq yd of carpet, and order padding by the same amount.
How many baseboards do I need for a 10x12 bedroom?
About 6 sticks of 8-ft baseboard. The 44-ft perimeter minus the 3-ft door leaves about 41 ft of trim, about 45 ft with waste; 45 ÷ 8 = 5.6, so buy six 8-ft sticks.
