Enter a patio's size and your paver's size and joint and get pavers, with a border if you want one, rounded up once, with the working shown for an example patio. A patio that is not a rectangle can be drawn with Draw a shape.

Patio: shape and size
Skip the drawingDrag a round corner to move it. The small hollow diamond on a side is its curve handle: drag it across the side to curve the side (it is not a corner). To add a corner (a new point), tap the side itself, then choose Add a point here. Tapping a corner or a side opens its actions. Drag empty space to move the view; pinch, or Ctrl and the mouse wheel, to zoom. The keys are listed under Keys.

Your project
Enter a size to see your total.
Each product is rounded up once for the whole project, so the total can be less than the items bought alone added together. A line counted from a cut layout (sheets, boards or tiles laid out piece by piece) is counted for each item and added.

Worked example: a patio
Show the working
- Patio area: length times width 12 ft × 12 ft = 144 ft²
- Pavers: area divided by one paver and its joint 144 ft² ÷ 32 in² = 648 pavers
- Add the waste allowance and round up once 648 pavers × 1.05 = 681 pavers

Pavers per square foot, by paver size and joint
Pavers in one square foot of patio for six paver sizes and four joint widths, before any waste
| Paver size | No joint | 1/8 in joint | 1/4 in joint | 3/8 in joint |
|---|---|---|---|---|
| 4 x 8 in | 4.5 | 4.3 | 4.11 | 3.93 |
| 6 x 6 in | 4 | 3.84 | 3.69 | 3.54 |
| 6 x 9 in | 2.67 | 2.58 | 2.49 | 2.41 |
| 12 x 12 in | 1 | 0.98 | 0.96 | 0.94 |
| 12 x 24 in | 0.5 | 0.49 | 0.48 | 0.48 |
| 16 x 16 in | 0.56 | 0.55 | 0.55 | 0.54 |
Each figure is 144 divided by the paver and its joint, length times width. The sizes are examples; type your own in the calculator.
Field and border pavers for the example patio
The example patio with a border of 6 in by 12 in pavers: field pavers and border pavers to buy by the number of border rows
| Border rows | Border band width | Field pavers | Border pavers |
|---|---|---|---|
| 0 rows | 0 in | 681 pavers | 0 pavers |
| 1 rows | 6 in | 572 pavers | 49 pavers |
| 2 rows | 1 ft | 473 pavers | 93 pavers |
| 3 rows | 1 ft 6 in | 383 pavers | 133 pavers |
A border of another paver size is its own line. The band is the rows times the border paver's width, on every side, and the field is what is left inside it.
Questions
How many pavers do I need?
Type the patio's size and your paver's length and width, with a joint if you leave one. The calculator divides the area by one paver plus its joint and adds your waste allowance, rounded up once.
How many pavers per square foot?
It depends on the paver size and the joint. The table gives the count for several sizes and joint widths, worked out from the size and joint.
How are border pavers counted?
Pick the number of border rows and, if the border paver is a different size, type it. The border band is the rows times the border paver's width on every side, and the field inside it is counted separately.
What about a circular patio?
Draw the circle with Draw a shape. The count is the area divided by one paver and its joint, so cuts along the curve are covered by the waste allowance, and a border is not counted for a curved outline.
