Design neat paths with precise paver counts everywhere. Estimate base, sand, edging, and costs quickly. Save time, avoid shortages, and finish your walkway beautifully.
| Scenario | Walkway | Paver | Depths | Waste | Key outputs |
|---|---|---|---|---|---|
| Metric sample | 10.00 m × 1.20 m | 20 cm × 10 cm, joint 0.5 cm | Base 10 cm, sand 3 cm | 7% | Area 12.00 m², pavers ≈ 600, base ≈ 1.20 m³, sand ≈ 0.36 m³ |
| Imperial sample | 32.80 ft × 4.00 ft | 8 in × 4 in, joint 0.25 in | Base 4 in, sand 1 in | 10% | Area 131.2 ft², pavers ≈ 595, base ≈ 1.62 yd³, sand ≈ 0.41 yd³ |
Examples are illustrative; your results change with units, joints, and patterns.
Measure length along the walkway centerline, then confirm width at several stations. For curves, use average width per segment and sum areas. Note steps, tree wells, or utility covers, because they increase cutting and waste beyond a simple rectangle.
This calculator treats each unit as (paver size + joint) in both directions. A 3–6 mm joint can reduce the raw paver count slightly, while tight joints demand careful screeding and consistent pavers. If you plan a border course, add a little extra waste for edge trimming.
Straight patterns typically waste less, while diagonal and herringbone layouts produce more off-cuts near edges. The built-in pattern factors model this cutting demand before waste is applied. Narrow paths amplify border cutting, so add 2–5% extra waste, especially for curves and end terminations.
Base and sand volumes are computed as area × thickness, but the installed thickness is the compacted thickness. Place base in lifts (often about 50 mm or 2 in), wet and compact each lift, and maintain a gentle cross-slope of roughly 1–2% for drainage. On soft soils, a geotextile separator can limit mixing and settlement, improving long-term joint stability.
Use pieces-per-box and boxes-per-pallet to translate totals into orderable units. If you price materials, the budget summary helps compare options such as thicker pavers versus deeper base. Example data you can copy:
Use 5–8% for straight, rectangular paths. Use 8–12% for diagonal, herringbone, borders, or curves. Add extra if you want spare pavers for future repairs and color matching.
The calculator adds the joint to each paver dimension to estimate effective coverage. Larger joints slightly increase coverage per unit, reducing the raw count, but they also require stable edging and consistent compaction.
Use Custom for mixed sizes, decorative bands, or complex borders. Start near 1.02–1.06 for moderate cutting and increase if your layout has many terminations, curves, or tight edge conditions.
Many foot-traffic installations use about 8–15 cm (3–6 in) of compacted base plus about 3 cm (1 in) bedding sand. Poor drainage, soft soil, or heavier loads usually require a deeper, well-compacted base.
Split the shape into rectangles or trapezoids, calculate each area, then add them together. For curves, use centerline length and average width by segment. Increase waste slightly for extra edge cuts.
Boxes equal the ceiling of total pavers divided by pieces per box. If you enter boxes per pallet, pallets equal the ceiling of boxes divided by boxes per pallet. Leave these fields blank if you purchase by piece.
No. Pricing is optional and only affects the cost summary. Leave price fields empty to compute quantities only, or add prices to compare material choices and confirm your purchasing budget.
