How do I work out how many pavers I need?

Divide the area you are covering by the face area of one paver, then round up. Say the patio is 12 ft by 10 ft, that is 120 square feet. A 12 in by 12 in paver covers exactly 1 square foot, so 120 divided by 1 is 120 pavers before any waste. With a 6 in by 6 in paver, one covers 0.25 square foot, so the same patio needs 480. The tool does the division and the rounding up for you so you never come up half a paver short.

Why add 10% waste and when should I change it?

Almost no area is a clean rectangle of whole pavers. The edges, curves and any column or drain force diagonal and partial cuts, and the offcut is usually too small to reuse. A 10% margin covers a simple square patio. Bump it to 15% for a herringbone or diagonal pattern where cuts are larger, and 5% is enough for a plain running-bond layout against straight walls. For a 120 square foot job at 1 square foot per paver, 10% turns 120 into 132.

My area is in feet but the paver is in inches — does that matter?

That is exactly how the real world labels them, so the tool keeps them separate. You read 12 by 10 off a tape measure in feet, and 12 by 12 off the paver box in inches. Internally it converts the paver face to square feet by dividing by 144 (there are 144 square inches in a square foot), then divides the area by that. Switch to metric and you enter the area in metres and the paver in centimetres instead.

How many pavers cover 100 square feet?

It depends on the paver size, which is why the tool shows pavers per square foot. With 12 in by 12 in pavers (1 square foot each) you need 100 before waste, 110 with a 10% margin. With 6 in by 6 in pavers (0.25 square foot) it is 400 before waste, 440 with 10%. With a 8 in by 4 in brick paver (about 0.222 square foot) you need roughly 450 before waste. Enter your real paver size and read the number straight off.

Does the calculator include the gaps between pavers?

No, and for most jobs that is the safer assumption. Sand-set pavers butt almost edge to edge, so counting by full face area slightly over-orders, which is what you want. If you are laying with wide mortar joints, say a 3/8 inch gap, the joints reduce the paver count a little, but the 10% waste margin already absorbs that and then some. Treat the result as a buy-this-many number, not a no-spares-allowed minimum.

How do I get the total cost?

Type a price per paver in the optional price field and the tool multiplies it by the rounded paver count, waste included. If your 132-paver patio costs 2.50 each, that is 330 for the pavers. The price line stays hidden while the field is 0 so the result is not cluttered when you only want a count. The figure is materials only, so add sand, base gravel, edging and delivery separately for a full job budget.

Order pavers for a backyard patio without coming up short

You measured the patio at 14 by 12 feet and the home-center paver is 12 by 12 inches. Punch both in, leave waste at 10%, and you get the buy-this-many number before you load the cart. No more standing in the aisle dividing 168 by something in your head, and no second trip across town because the run came up eight pavers shy on the last row.

Quote a paving job for a client

A client wants a 20 by 15 foot driveway apron in a herringbone pattern. Set waste to 15% for the heavier diagonal cutting, enter your paver size, and read the count. Add a price per paver and the tool returns a materials subtotal you can drop straight into the quote, then add base, sand, edging and labor on top of a number that holds up.

Compare two paver sizes before you commit

The 6 by 6 inch paver looks cheaper per piece than the 12 by 12, but it takes four times as many to cover the same ground. Enter each size in turn, read pavers per square foot and the total at your price, and the per-paver bargain often loses once you multiply by the count and the extra laying time.

Estimate a tiled floor or a garden path

The same area-over-tile math covers an indoor floor tile order or a stepping-stone garden path. Enter the room or path footprint, the tile or stone size, and a waste margin sized to the cut difficulty, and the count maps straight to how many boxes or stones to buy.

Enter the area you are covering and the size of one paver — the tool divides them, rounds up to whole pavers and adds a waste margin for cuts and breakage. Area is in feet (or metres); the paver is in inches (or centimetres), exactly how each is labelled on the tape measure and the box.

What this tool does

Free paver calculator that tells you how many pavers, patio stones, bricks or floor tiles to buy for a given area. Enter the space you are covering as length by width, enter the size of one paver, and the tool divides the area by the paver face, rounds up to whole pavers and adds a waste margin (10% by default) for diagonal cuts, edge pieces and the cracked one at the bottom of the pallet. Area dimensions go in feet or metres; the paver goes in inches or centimetres, exactly how each is labelled on the tape measure and the box. You also get pavers per square foot and per square metre so you can sanity-check against the coverage printed on the pallet, plus an optional total cost when you type a price per paver. Everything runs in your browser with one-click copy and a shareable URL that reopens your exact area, paver size and waste setting. 100% client-side, no upload.

Common pitfalls

Entering the paver size in feet instead of inches. A 12 inch paver typed as 12 feet makes one paver cover 144 square feet, so the tool tells you to buy one paver for a whole patio. The paver field is labelled in inches (or centimetres in metric) for this reason — read the size off the box, not the tape measure.
Ordering exactly the calculated minimum with zero waste. Set waste to 0 and a single mis-cut on the last row sends you back to the store, where that batch may now be a different dye lot. Keep at least 5% so spare pavers from the same pallet are sitting in your garage when you need one.
Forgetting the result is materials only. The paver count does not include the base gravel, bedding sand, edge restraint or jointing sand a real install needs. Use the count for the pavers, then budget the sub-base separately so the truck arrives with everything.

Privacy

Every calculation — the area, the divide-by-144 paver face, the rounding up, the waste margin and the optional cost — is plain JavaScript that runs in your browser tab. No measurement, paver size or price ever leaves the page, and nothing is logged. The one caveat: the shareable URL encodes your area, paver size and waste in the query string, so a share link pasted into chat records those dimensions in the recipient server's access log. The price you type stays local and is never put in the URL. For a confidential client estimate, use the copy button and paste the text.
