Frequently asked questions
How many 12x12 pavers do I need for 200 sq ft?
At a 10% waste allowance, 200 sq ft needs about 220 pavers of 12×12 inch size.
Why add waste for pavers?
Cuts around edges, curves, and borders - plus occasional breakage during installation - typically use about 10% more pavers than the flat area math suggests.
How much sand or base material do I need under pavers?
A typical base is 4-6 inches of compacted gravel topped with 1 inch of leveling sand, though exact depth depends on soil conditions and whether the area will bear vehicle weight - this calculator estimates paver count only, not base material.
Can this calculator handle an irregular or curved patio shape?
This calculator works from a total square footage figure, so for irregular or curved layouts, break the area into simpler rectangular or triangular sections, calculate each section's square footage separately, add them together, then enter the combined total.
How many 8×16 inch pavers do I need for a 150 sq ft patio?
Each 8×16 inch paver covers about 0.89 sq ft (8×16÷144). With a 10% waste allowance, 150 sq ft needs about 165 sq ft of coverage, which comes out to roughly 186 pavers.
Does paver shape or pattern change how much waste allowance I should use?
Yes - a simple running-bond pattern with square or rectangular pavers typically needs only the standard 10%, but herringbone or basket-weave patterns, or borders that require many angled cuts, can need 15% or more since more pieces get trimmed and discarded.
How is a paver calculator different from a tile calculator?
The math is similar - both divide a waste-adjusted area by each unit's coverage - but pavers are laid outdoors over a compacted gravel and sand base rather than adhered with grout lines like tile, so this calculator doesn't add a grout-line spacing factor the way the tile calculator does.
