Plan excavation, base, bedding, pavers or slab concrete, edging, and finish materials for a residential patio.

Quick presets

Inputs

1 Geometry and layout 1 group

Set the footprint and primary layout path before fine-tuning quantities and finishes.

Patio layout

Patio Surface Type Layout Mode Use quick estimate when you only know area + perimeter. Use shape-aware mode when you can enter actual rectangle or L-shape dimensions. Shape Preset Overall Length (ft) Type it the way you measured it - 16' 6" or 16.5 both work. Overall Width (ft)

16 columns × 12 rows of whole units: 15 ft 11 in × 11 ft 11 in. Approximate boundary reduction: 0.66 in at each end and 0.51 in on each side. Planning assumption: 1/8″ internal joints; excludes perimeter clearance for installation. Check the selected product’s joint requirements.

2 Structure and support 1 group

Open this stage after choosing a preset or locking the geometry baseline.

Base and bedding

Base Thickness (in) Starts at 6 in so the default patio stays in the calculator's conservative base band before region-specific frost review.

Include geotextile fabric

Concrete slab

3 Finish and pricing 3 groups

Refine finish and region only after the rest of the plan is clear.

Pavers and edging

Paver Size Pattern waste stays lower on simple modules and rises as the unit gets smaller or the layout gets more cut-heavy. Paver Pattern Paver Waste Setting Pattern default follows the selected paver pattern; custom lets you override it for unusual site cuts or reuse conditions. Edging Type

Include polymeric sand

Finish and protection

Include sealer

Regional settings

State / Pricing Region

Scope first Choose quick estimate only while the footprint is still rough. Switch to shape-aware mode before you lock drainage edges, thresholds, or cutouts.

Quick estimate is best for early budgeting; shape-aware layout is better once the real patio outline is known.
Confirm slope away from the house and door-threshold transitions before locking the finished patio edge.

Planning rules & code notes U.S. planning assumptions, pricing coverage, and permit-sensitive notes for this calculator.

This calculator uses common residential assumptions for spacing, waste, and coverage. Confirm site conditions and local code before ordering.
Regional pricing and frost guidance currently cover selected states. If your saved state falls outside coverage, the calculator keeps it visible and falls back to calculator default pricing instead of silently switching regions.
L-shape cutout inputs are kept inside the overall patio rectangle rather than letting the preview spill outside the footprint.

Planning assumptions · 7

Base gravel converts at about 1.40 tons per cubic yard, so verify local aggregate density and supplier packaging before ordering.
Excavation reports bank volume plus a loose-spoil planning volume using a nominal 20% swell factor for haul-off and staging checks.
Slope paver patios away from the house by about 3/16 in to 1/4 in per ft, and confirm drainage, soils, frost, and local code before construction.
Shape-aware mode uses your entered rectangle dimensions directly for area, perimeter, edging, control-joint planning, and preview geometry.
Paver waste follows the straight lay / large-format grid default of 8%.
Edging is planned for the full perimeter; if a side runs against a wall or existing slab, you may need less.
Paver excavation assumes the finished surface settles about 1/4 in into the bedding layer and ends roughly flush with adjacent grade.

Concrete Paver Sizes

Residential patios typically default to 2-3/8 in (60 mm) concrete pavers in this calculator. Heavy vehicular areas need separate design review.

Nominal size	Actual dimensions	Thickness	Common use	Planning rule
4x8 Holland	3.94 in x 7.87 in	2-3/8 in (60 mm)	Classic brick pattern and walkways	A very common homeowner choice for modular layouts.
6x6	5.9 in x 5.9 in	2-3/8 in (60 mm)	Square modern layouts	Simple installation and repeatable cuts.
8x8	7.8 in x 7.8 in	2-3/8 in (60 mm)	Medium-format patio	Balances speed and visual rhythm.
12x12	11.8 in x 11.8 in	2-3/8 in (60 mm)	Large-format residential patio	A common main-field patio size.
16x16	15.7 in x 15.7 in	2-3/8 in (60 mm)	Large smooth patio field	Modern appearance with fewer joints; calculator keeps a wider base extension.
24x24	23.6 in x 23.6 in	2-3/8 in (60 mm)	Oversized slab-style look	Luxurious look, but handling, flatter base prep, and edge support deserve extra care; some manufacturers sell similar slabs in thinner 50 mm formats.

Paver Pattern Waste Rules

Pattern choice now drives the default waste allowance. Custom waste remains available when field conditions are less typical.

Pattern	Default waste	Typical range	Planning rule
Straight lay / grid	8%	5% to 10%	Best baseline for simple rectangular patios with moderate edge cuts.
Running bond	8%	6% to 12%	Common modular pattern with predictable half-bond cuts.
Diagonal	12%	8% to 16%	More perimeter cutting and waste than straight-lay layouts.
Herringbone	14%	10% to 18%	Most conservative default because edge cutting rises quickly.

Base and Bedding Layers

The calculator assumes dense-graded base gravel and keeps paver bedding sand at 1 in max using washed concrete sand, not stone dust or masonry sand.

Layer	Material	Recommended compacted thickness	Planning rule
Sub-base	3/4 in minus / road base	4 in to 6 in for light patios	Compact in about 2 in to 3 in lifts rather than dumping the whole depth at once.
Bedding sand	Washed concrete sand	1 in max	Screed smooth and do not use bedding sand, stone dust, or masonry sand to correct a weak base.
Geotextile	Woven stabilization / separator fabric	Installed between soil and base	Strongly recommended where softer native soils could contaminate the compacted base.

Edging and Restraints

This calculator prices plastic and metal restraint systems. Concrete edge restraint remains a reference-note installation option, not a priced BOM path.

Type	Typical size	Material	Planning rule
Plastic paver edging	About 6 ft sections	Rigid or flexible PVC	Secure with 10 in spikes at about 8 in to 12 in spacing.
Metal edging	About 6 ft sections	Aluminum	More rigid and lower-visibility for straight, modern layouts.
Concrete edge restraint	Field-applied	Mortar or concrete	Reference-only installation method in this calculator, not a priced BOM item.

Concrete Slab Patio

A 4 in slab is still the default residential assumption, but this calculator now surfaces reinforcement, formwork, curing, and finish choices rather than hiding them in notes only.

Item	Specification	Planning rule
Slab thickness	4 in standard residential patio; 5 in to 6 in for heavier-duty uses	4 in remains the calculator default.
Base	2 in to 4 in compacted gravel base	Calculator defaults to a 4 in compacted base because it improves drainage and slab support.
Reinforcement	6x6 W1.4/W1.4 wire mesh or #3 rebar @ 16 in to 18 in o.c.	Calculator scope now prices reinforcement material when selected.
Formwork	2x4 perimeter forms	Calculator scope can add basic perimeter form boards.
Control joints	Every 8 ft to 12 ft; depth about 1/4 slab thickness	Calculator outputs joint counts, total lf, and target joint depth as layout metrics.
Finish and curing	Broom / light trowel / salt finish + curing method	Modeled as configurable planning scope, not just a buried footnote.

Drainage and Layout Rules

Drainage slope: Paver patios should slope about 3/16 in to 1/4 in per ft; concrete slab patios should slope about 1/8 in to 3/16 in per ft. Never plan a dead-flat patio surface.
Layout modes: Use quick estimate when you only know area + perimeter. Use shape-aware mode when you can enter actual rectangle or L-shape dimensions.
Base extension: For pavers, the compacted base extends by the larger of the entered base thickness or a size-based minimum per side.
Excavation rule: Paver excavation assumes about 1/4 in of final settlement into the bedding layer and keeps the finished surface roughly flush with adjacent grade in this calculator.
House clearance: Keep the finished patio below siding, stucco screeds, brick weeps, and similar moisture-sensitive transitions; a 2 in to 4 in clearance band is a common planning checkpoint.
Utility locate: Call 811 before excavation. Even shallow patio digging can hit irrigation, telecom, low-voltage, or branch electrical runs.
Regional coverage: Patio pricing and frost rules currently cover a limited list of states. Unsupported states fall back to calculator defaults with a warning.
Disclaimer: Verify local code, frost depth, drainage, soils, and exact supplier dimensions before ordering.

All dimensions follow common U.S. nominal-versus-actual patio material conventions. This calculator now supports both quick-estimate and shape-aware patio layouts, keeps paver patterns and waste rules explicit, and makes slab reinforcement / formwork / curing scope visible. Regional pricing and frost guidance still cover a limited set of states, so always confirm drainage, frost, soil conditions, local code, and exact supplier specs before ordering.
