Inputs
ℹ️L-Shaped models a main run plus a second connected section — an apron, turn, or widened area — as two rectangles added together.
ℹ️Distance from the street/curb to the garage or parking area.
ℹ️Single-car driveways are typically 10-12 ft wide; double-car driveways are typically 20-24 ft.
Aggregate Base
ℹ️8 in is standard for residential driveways; go to 10 in for soft/clay soil or heavy vehicles. 6 in is CMHA's minimum, only on well-drained soil.
ℹ️Standard dump trucks carry around 10-12 tons per load. Applies to the aggregate base, always bulk-delivered.
Bedding Sand
ℹ️1 in is the standard bedding thickness — deeper loose sand can shift and settle unevenly.
ℹ️Bulk delivery is standard; bagged is only practical for a small area or patch.
Pavers
ℹ️60mm is OK for standard residential driveways (product-dependent); 80mm is preferred/required for heavier vehicular loads. 30mm is overlay-only, not rated for any vehicle.
ℹ️Running bond has the lowest cutting waste and works with any paver shape; herringbone and basket weave are designed for roughly 2:1 rectangular pavers.
Joint Sand
ℹ️Joint depth is set to your paver thickness — joints are filled to the full depth of the paver.
Geotextile Fabric & Edge Restraint
Standard practice between subgrade and base — prevents soil migration into the base and reduces long-term rutting.
Edge restraint is required for an interlocking paver driveway to perform correctly — pick "No" only if a suitable restraint already exists or will be quoted separately, not to skip it from the actual build.

Assumptions Used
Standard US residential paver driveway, rectangular or L-shaped, built as an aggregate base, a screeded bedding sand layer, interlocking pavers, and swept-in joint sand — with edge restraint required around the perimeter to keep the system from spreading under vehicle loads. The aggregate base weight uses a 15% compaction allowance and 8% waste, matching the site's general gravel-weight calculator; bedding sand carries only a 10% screeding/leveling waste allowance since it is installed loose, not compacted. Paver count and cost are based on the order area (footprint plus your chosen layout pattern's cut waste). Joint sand quantity is derived from the actual joint geometry (paver size, joint width, and paver thickness as joint depth), plus a 12% allowance for the repeated dry fill-and-compact passes needed to fully pack every joint before water activation. Geotextile fabric area includes a 10% overlap allowance for seams; standard roll size is 12.5 × 360 ft. Edging length sums each section's own full perimeter — for L-shaped mode this is a conservative over-estimate. This calculator computes material quantities only — it does not verify subgrade compaction adequacy, local drainage requirements, or structural design for unusual soil or loading conditions.

What Is a Paver Driveway Calculator?
A paver driveway calculator finds the aggregate base, bedding sand, paver count, joint sand, geotextile fabric, and edge restraint needed for an interlocking paver driveway — rectangular, or L-shaped with a main run plus a connected apron or turn — built as a real layered system, not a single area-times-coverage guess. Most online paver calculators only estimate paver count from area; this one also models the base and bedding layers underneath, plus the actual joint-sand volume from your paver geometry.
This calculator computes material quantities only. It does not verify subgrade compaction adequacy, local drainage requirements, property line/setback compliance, or structural design for unusual soil or loading conditions.
Building a residential patio instead of a driveway? This calculator's depths and thicknesses are sized for vehicular loads — for a pedestrian-only patio, try the Patio/Paver Materials Calculator instead, which also supports Mortar-Set installation and Natural Flagstone.
Why base, bedding sand, and pavers are treated differently:
- The aggregate base is compacted in lifts before anything else, so it carries a compaction allowance — bedding sand is deliberately left loose and screeded, so it only carries a leveling waste allowance, not a compaction one
- Paver count and cost are based on the order area, which includes your layout pattern's own cut-waste percentage — running bond wastes far less than herringbone
- Joint sand quantity comes from the actual joint geometry (paver size, joint width, joint depth) rather than a flat coverage guess, plus an allowance for the repeated dry fill-and-compact passes needed to fully pack every joint
- Edge restraint is required, not optional, for an interlocking paver driveway — without it, pavers spread apart and joints open under vehicle loads, unlike a gravel driveway where edging is a nice-to-have
Paver Driveway Calculator Formula: How Is It Determined?
Each layer is calculated using its own real construction logic, then combined into one material takeoff.
Step 1 — Aggregate Base
Volume = Area x Base Depth
Weight = Volume x (1 + 15% compaction) x Material Density x (1 + 8% waste)
The base is compacted in lifts before the bedding sand goes down, so it gets the same 15% compaction and 8% waste allowances used across the site's driveway calculators.
Step 2 — Bedding Sand
Volume = Area x Bedding Sand Depth
Weight (or Bags) = Volume x (1 + 10% screeding waste)
No compaction allowance — bedding sand is screeded level and left loose; the pavers themselves plus a final compactor pass on the finished surface consolidate it, not a pre-compaction step.
Step 3 — Pavers
Order Area = Driveway Area x (1 + Pattern Waste %)
Pavers = ceil(Order Area / Paver Unit Area)
Pattern waste ranges from about 5% (running bond) to about 13% (45° herringbone), reflecting how much border-cut offcut each pattern actually produces.
Step 4 — Joint Sand
Joint Volume per sq ft = 144 x (1/Paver Width + 1/Paver Length) x Joint Width x Joint Depth
Bags = ceil(Total Joint Volume x (1 + 12% sweep-in) / Bag Yield)
Derived from the actual joint geometry at your paver size, using the installed footprint (not the paver order area, since cut offcuts don't create extra joints). Joint depth is set to your paver thickness.
Step 5 — Fabric & Edge Restraint
Fabric Rolls = ceil(Area x (1 + 10% overlap) / Roll Area)
Edge Restraint Length = Sum of each section's own 2 x (Length + Width)
Fabric is priced per whole roll actually purchased. Edge restraint is required for this calculator's driveway type, and for L-shaped mode sums both sections' full perimeters as a conservative over-estimate.
Worked Example
This example walks through your current inputs above, using the same steps as the Formula section.
Input Values Used
| Input | Value | Why it is used |
|---|---|---|
| Shape | 20 ft / 10 ft | Sets area for every layer |
| Layers | 12.2" total (8" base + 1" bedding sand + 3.15" paver) | Sets volume and weight per layer |
| Paver / Pattern | 4 x 8 in (Standard Brick), Running Bond (Stretcher) — lowest waste | Sets order area, paver count, and joint geometry |
Step 1 — Aggregate Base
| Calculation | Result |
|---|---|
| Volume = 200 sq ft x (8/12) ft | 133.33 cu ft (4.94 cu yd) |
| Weight = Volume x (1 + 15%) x density x (1 + 8%) | 9.563 tons |
| Truck loads = ceil(9.563 / 10) | 1 loads |
Step 2 — Bedding Sand
| Calculation | Result |
|---|---|
| Volume = 200 sq ft x (1/12) ft | 16.67 cu ft (0.62 cu yd) |
| Weight = Volume x (1 + 10%) x density | 1.03 tons |
Step 3 — Pavers
| Calculation | Result |
|---|---|
| Order Area = 200 sq ft x (1 + 5%) | 210 sq ft |
| Pavers = ceil(Order Area / 0.2222 sq ft per paver) | 945 pavers |
Step 4 — Joint Sand
| Calculation | Result |
|---|---|
| Joint volume (0.125" wide x 3.15" deep) | 2.46 cu ft |
| Bags = ceil(Volume x (1 + 12%) / 0.5 cu ft per bag) | 6 bags |
Therefore, this 20 ft x 10 ft paver driveway needs approximately 945 pavers and 10.593 tons of bulk aggregate base, 6 bags of joint sand.

Paver Driveway Reference Tables
Typical layer depths, layout pattern waste, and joint width guidance.
| Layer | Typical Depth | Notes |
|---|---|---|
| Aggregate base | 6-10 in | Compacted in 2 in lifts, crusher-run / quarry-process material — CMHA minimum for a driveway is 6 in |
| Bedding sand | 1-1.5 in | Screeded level, left loose — NOT compacted before pavers |
| Pavers | 60-80mm (2.4-3.1 in) | 60mm is OK for standard driveways (product-dependent); 80mm is preferred/required for heavier vehicular loads |
Layout Pattern Waste Comparison
| Pattern | Typical Waste | Notes |
|---|---|---|
| Running Bond | ~5% | Straight cuts often reuse at the opposite row end — lowest waste |
| Basket Weave | ~8% | Moderate waste from border cuts |
| 90° Herringbone | ~10% | Straight cuts along two edges, angled on the other two |
| 45° Herringbone | ~13% | Angled cuts at every border edge — highest waste, most striking look |
Edge Restraint Material Comparison
| Material | Typical Service Life | Notes |
|---|---|---|
| Steel / Aluminum | 15-50+ years | Holds curves well, longest-lasting |
| Poured Concrete | Long / permanent | Most rigid, highest install cost |
| Plastic | Shorter | Budget option, lower durability under vehicle contact |
| Landscape Timber | 10-15 years | Cheapest, easiest DIY install |
When should you use this paver driveway calculator?
- Planning aggregate base, bedding sand, paver count, and joint sand quantities before ordering material for a full driveway build.
- Comparing how much extra material different layout patterns (running bond vs. herringbone vs. basket weave) actually need.
- Sizing geotextile fabric rolls and edge restraint material alongside the paver system itself.
- Scheduling aggregate base delivery by knowing how many truck loads it needs.
- Cross-checking a contractor's paver driveway material quote against an independent estimate.
Quick Paver Driveway Tips
- Call 811 (or your local utility locate service) before any excavation for the driveway or its base.
- Screed bedding sand level and leave it loose — don't compact it before laying pavers, or you'll get an uneven surface.
- Install edge restraint before sweeping in joint sand, not after — it's what keeps the whole system from spreading under vehicle loads.
- Fill and dry-compact joint sand in repeated passes until every joint is fully packed — never mist or wet the sand between passes.
- Sweep or blow ALL excess joint sand off the paver surface before activating with water — leftover surface sand will bond and haze once wetted.
- Choose running bond over herringbone if minimizing material waste matters more than the visual pattern.
- Confirm at least 60mm paver thickness (product rated for vehicular use) for a standard driveway, and step up to 80mm for RVs, trucks, or frequent heavy traffic.
Common Mistakes
- Compacting bedding sand before laying pavers, which prevents pavers from settling evenly into a flat surface.
- Skipping edge restraint, letting pavers spread apart and joints open under vehicle loads over time.
- Using 30mm overlay-only pavers, or an unrated 60mm product, on a driveway carrying vehicle traffic.
- Only sweeping joint sand once, leaving joints under-filled after a single dry-compaction pass.
- Activating polymeric sand with water before all excess sand is cleaned off the paver surface, causing hazing or residue bonded to the pavers.
- Using mason sand instead of concrete sand for the bedding layer, risking pumping and water retention issues.
- Not accounting for a herringbone pattern's higher cut waste when ordering pavers, leading to a mid-project shortfall.
- Skipping geotextile fabric, letting the base stone gradually migrate into the subgrade soil below.
Limitations
- Standard US residential paver driveway, rectangular or L-shaped (two rectangular sections) — a driveway with curves or a third connected section needs separate calculation for that additional section.
- For L-shaped mode, edge restraint length sums both sections' full perimeters, a conservative over-estimate that doesn't subtract the shared internal edge.
- One paver size, thickness, and layout pattern applies across the entire driveway — a design mixing multiple paver specs needs separate calculation per zone.
- Compaction (15%) and waste (8%) allowances for the aggregate base, and the 10% bedding sand and 12% joint sand allowances, are fixed assumptions, not user-adjustable per layer.
- Does not verify subgrade compaction adequacy, local frost depth requirements, or drainage/grade compliance.
- Cost estimation covers base, bedding sand, pavers, joint sand, fabric, and edge restraint material only — excavation, subgrade compaction labor, and installation labor are not included.
