Free and simple, type your wall's length and height and get how many bricks to buy, with 10% extra for cuts and breakage already added. No sign-up, no email.
Step 1: Measure your wall: length and height in feet.
Step 2: Pick your brick size. If you are not sure, keep "Standard", it is the most common house brick in the USA.
Step 3: Press Calculate. You get the bricks to buy and a rough mortar estimate.
Step A: Wall area = Length × Height. Example: 10 × 8 = 80 sq ft.
Step B: A standard brick with its mortar joint covers about 6.55 bricks per sq ft. Example: 80 × 6.55 = 524 bricks exact.
Step C: Add 10% for cuts and breakage: 524 × 1.1 = 577 bricks to buy.
| Wall | Exact Bricks | Bricks to Buy |
|---|---|---|
| 5 × 4 ft (20 sq ft) | 131 | 145 |
| 10 × 8 ft (80 sq ft) | 524 | 577 |
| 10 × 10 ft (100 sq ft) | 655 | 721 |
| 20 × 8 ft (160 sq ft) | 1,048 | 1,153 |
This is for a single-layer wall (one brick thick, like a veneer or garden wall). A double-layer wall needs twice as many bricks.
1. Forgetting the mortar joint. A brick is never laid touching the next one, the ⅜ inch mortar joint makes each brick cover more area. Counting bricks without the joint gives you far too many.
2. No extra bricks. Bricks get cut at every end and corner, and some arrive broken. The 10% extra here is not optional in a real job.
3. Mixing wall types. This answer is for a single-layer wall. If your wall is two layers thick, double the answer.
4. Trusting the mortar number too much. Mortar use changes with the joint size and the worker. Treat the bag count as a starting estimate and check the coverage printed on your bag.
About 6.55 standard bricks per sq ft, including a standard ⅜ inch mortar joint. Bigger bricks cover more area, so they need fewer per sq ft.
655 standard bricks exact, and 721 to buy with the normal 10% extra for cuts and breakage.
Roughly one 80 lb bag of mortar mix for every 100 standard bricks. It is an estimate, always check the coverage printed on your bag.
No. This is for upright walls. Pavers lie flat and cover a floor area, so they are counted a different way.
Subtract the door or window area (length × height) from the wall area, then use that smaller area in this calculator.
