Patio Calculator: 185 Pavers Needed for 14x12 ft Patio
On the defaults — a 14 ft by 12 ft patio, 12 in pavers, 10% waste — you need 185 pavers. This is the patio tool: measure the patio once, allow for the cuts, and buy the pavers once — a half-paved patio waits for no second delivery.
What does patio pavers needed 185 pavers mean?
It means one hundred and eighty-five pavers pave a 14 ft by 12 ft patio with room for cuts. The patio itself is 168 square feet, since 14 times 12 is 168; one 12 inch paver covers exactly 1 square foot, so the exact need is 168 pavers, and with 10% waste for cuts and breakages that becomes 184.8, rounded up to 185 whole pavers because pavers are sold by the paver, not by the fraction. The spare pavers are not spare stock exactly — they are the pavers the edges and corners consume in cutting, so a patio paved to the exact count runs short before the last corner.

Three things to check before you trust the number
First, check the paver size you are actually buying: 12 in is the common patio paver, but a 6 in paver covers only a quarter of a square foot and raises this patio to 740 pavers, and a 24 in paver covers 4 square feet and drops it to 47 pavers. Second, remember the count follows the area, not the length alone: a 14 ft by 12 ft patio is 168 sq ft, and a patio measured by one side under-orders. Third, judge the waste honestly: straight edges fit 10%, but a curved edge or a herringbone pattern can want 15%, since every angle takes a cut. Sand, edging and base are bought separately — see the sand calculator for the base under a patio like this one.
Worked example
14 ft long, 12 ft wide, 12 in pavers, 10% waste. Area: 14 × 12 = 168 sq ft. Paver area: (12 ÷ 12) × (12 ÷ 12) = 1 sq ft. Pavers exact: 168 ÷ 1 = 168. With waste: 168 × 1.10 = 184.8, rounded up to 185 pavers. In practice that means buying 185 pavers, and expecting the last few to go on edge cuts and the odd breakage. If the same patio used 6 in pavers instead, the need would rise to 740 pavers, but the patio paved would be identical.
Every branch, checked
With a 16 ft long patio instead of 14 ft, the area rises to 192 sq ft and the need to 212 pavers. With a 14 ft wide patio, the area rises to 196 sq ft and the need to 216 pavers, since the patio area is the same either way only when the sides match. With 6 in pavers, the area stays 168 sq ft but the need rises to 740 pavers, since every paver covers a quarter of the ground. With 5% waste, the exact need stays 168 pavers but the buy falls to 177 pavers. Patio size, paver size and waste each move the order on their own, so a wrong paver figure is as costly as a wrong measurement.
The reverses, worked backwards
The length behind 185 pavers is 14 ft: at 12 ft the need is 159 pavers (12 ft × 12 ft patio, 12 in pavers, 144 sq ft, 144 pavers exact, 10% waste); at 16 ft it is 212 pavers (16 ft × 12 ft patio, 12 in pavers, 192 sq ft, 192 pavers exact, 10% waste). The paver size behind 185 pavers is 12 in: at 6 in the need is 740 pavers (14 ft × 12 ft patio, 6 in pavers, 168 sq ft, 672 pavers exact, 10% waste); at 24 in it is 47 pavers (14 ft × 12 ft patio, 24 in pavers, 168 sq ft, 42 pavers exact, 10% waste). The waste behind 185 pavers is 10%: at 5% the need is 177 pavers (14 ft × 12 ft patio, 12 in pavers, 168 sq ft, 168 pavers exact, 5% waste); at 15% it is 194 pavers (14 ft × 12 ft patio, 12 in pavers, 168 sq ft, 168 pavers exact, 15% waste). Each reverse moves one input and holds the rest, so the step is exactly one dimension, paver or waste change.
What the defaults assume
The defaults assume a 14 ft by 12 ft rectangular patio, square 12 in pavers, and 10% waste for cuts and breakages. They do not assume sand, edging, base or steps — a patio with steps counts its step pavers separately, and the base is bought by the yard, not by the paver.
Who uses this
- A homeowner laying a patio: the 185-paver order settles the yard call before the first paver is laid.
- A DIY builder paving a garden patio: the same maths on the patio alone gives the pavers, not a whole yard.
- A contractor quoting a job: patio area, paver size, waste — the quote follows the same three steps, and the waste line shows the client why.
- A landlord budgeting a patio refit: the patio size off the plans, multiplied out, gives the paver line on the refit budget.
Accuracy & limitations
The arithmetic is exact for the inputs entered; the judgement is the paver size and the waste. Real patios have curves, angles and steps, and the paver on the pallet overrides any planning figure; a patio measured gross over-orders, and a waste figure read off a straight-edge job under-orders a curved one. Treat 185 pavers as the planning order for a 14 ft by 12 ft patio at 12 in pavers and 10% waste, and allow 15% for a curved edge or a herringbone pattern.

Frequently asked questions
How many pavers do I need for a 14x12 ft patio?
185 pavers at 12 in pavers and 10% waste. The area is 168 sq ft; at 1 sq ft per paver that is 168 pavers exact, and 168 × 1.10 = 184.8, rounded up to 185.
How do I work out pavers from a patio size?
Multiply length by width for the area, divide by the area of one paver, add the waste and round up. A 14 ft by 12 ft patio is 14 × 12 = 168 sq ft, or 185 pavers at 12 in and 10% waste.
How much waste should I allow for pavers?
10% for straight edges, 15% for curves or a herringbone pattern. Every angle takes a cut, so the waste moves the order directly.
Does this count the sand and base too?
No — this calculator counts pavers only. Sand, edging and base are counted separately, by the patio.
Should I buy the exact pavers or round up?
Round up: pavers are sold by the paver, and the spare pavers are the cutting stock. A patio paved to the exact count runs short before the last corner.
What if my patio is not a rectangle?
Split it into rectangles, work out each area, and add them before dividing by the paver area. The square footage calculator handles the area step section by section.
