Patio Paver Edge Restraint Planner
Paver area does not tell you how much approved edge restraint to buy. Each included side is rounded up separately, with no assumed sharing of leftover cuts. Measure the straight sides that actually require restraint, then convert linear feet into whole stock pieces. The calculator does not approve an edge design.
Different from our regular Paver Calculator
For material units, base aggregate and bedding sand volumes, use the Paver Calculator. Read Paver Materials for Patios to compare interlocking concrete pavers, clay brick and natural stone, including construction and water-management differences.
The Concrete Masonry & Hardscapes Association's edge-restraint technical note explains why edges are part of a functioning interlocking pavement system. This tool computes lengths only. It does not choose a structural fastening method, guarantee that all straight sides need the same product, or handle nonrectangular boundaries, curves and corners automatically.
Why a 56-foot perimeter can require eight stock pieces
A 16-by-12-foot rectangle has a 56-foot perimeter. With eight-foot stock and all four edges selected, this planner rounds each edge separately: two pieces for each 16-foot edge and two for each 12-foot edge. That is eight pieces, not the seven obtained by dividing the combined perimeter by eight.
The model does not assume offcuts can be reused or joined across edges. If two adjoining boundaries already have suitable restraint and are excluded, the remaining 16-foot and 12-foot edges need two pieces each, or four pieces. Excluding an edge only makes sense when its actual restraint is accounted for.
Check before the next step
Verify the boundary condition, connectors, corner detail and fixing spacing required by the selected system. Confirm any offcut reuse with an actual cut plan rather than reducing the order from the perimeter total alone.
