How Many Pavers Do You Need? A Patio-by-Patio Guide
How to figure out exactly how many pavers a patio needs, why laying pattern changes the waste factor, and how paver size affects the count.
Paver counts go wrong in one of two places: skipping the waste factor for cuts along the edges, or forgetting that laying pattern changes how much of that waste you'll actually have.
The formula behind the estimate
Patio area = length × width. Add a waste factor (10% for a straight running-bond pattern, 15% or more for herringbone or diagonal layouts), then divide by the coverage of a single paver — a 12×12 in paver covers exactly 1 sq ft, which makes it the easiest size to estimate by hand.
Why laying pattern matters so much
A straight pattern lines pavers up in simple rows, so almost every cut piece at the edge is a clean rectangle with little waste. Herringbone and basketweave patterns interlock at an angle — which looks better and locks together more strongly under load — but every edge produces an angled offcut that usually can't be reused elsewhere on the same patio.
Don't forget the base underneath
- Compacted base: typically 4 inches for a patio, deeper for anything vehicles will drive on.
- Sand setting bed: a thin 1-inch screeded layer the pavers actually sit on.
