The length of the driveway.
Measure from the street or garage to the far end of the driveway.
Tools needed: Tape measure or measuring wheel
The width of the driveway.
A single-car driveway is typically about 3 m (10 ft) wide; double-car driveways are 5.5-6 m (18-20 ft).
4 in (~0.1 m) minimum, 5-6 in (~0.13-0.15 m) if it will carry heavier vehicles.
Thicker slabs cost more but resist cracking under heavier vehicle loads better.
A compacted gravel base improves drainage and reduces cracking from ground movement.
4-6 in (~0.1-0.15 m) is standard. Set to 0 if your soil and local practice don't call for a gravel base.

How this was calculated
Formula source(s)
- Residential driveways commonly use a 4-6 in concrete slab over a 4-6 in compacted gravel base for drainage and stability
- Volume formula: length x width x depth / 27 = cubic yards

- 10 ft
- Concrete Thickness
- 5 in
- Gravel Base Thickness
- 4 in
Intermediate steps

- 390 sq ft
- Gravel base needed
- 4.81 yd³
What this calculation does not cover
- Area comes from length multiplied by width alone, so a flared apron at the street, a turning bay or a curved edge has to be measured and added on as its own rectangle.
- Your single thickness figure is applied evenly over that whole area, which leaves out the thickened edge or turn-down many driveways carry around the perimeter.
- Both volumes are the neat geometric quantity with no waste percentage folded in, so spillage, an uneven subgrade and the increment your ready-mix supplier actually delivers in still have to be covered on top.
- The gravel line reuses the slab rectangle at the compacted thickness you entered, counting no over-dig past the slab edge and no bulking allowance for stone that arrives loose and is then rolled down.
- That base figure stays a volume because no density is applied to it, so a supplier quoting by weight needs its own conversion for the aggregate you have chosen.
- Thicknesses are taken as given rather than checked against your soil, frost depth or the vehicle weights the slab will carry, and reinforcement, forms and control joints sit outside the arithmetic entirely.
Estimated cost — your price
This site holds no price list for this material — local prices vary too much to publish honestly. Enter your supplier's price and the result is costed with it.
Every band is at the thickness you entered, and the vertical scale is the horizontal scale — so a thin course looks thin. The width shown is a fixed slice; this drawing is about depth.

Tools and safety for this job
To place and finish concrete and lay paving. Generic types, no brands, no prices.
Protection this work requires
- Cutting or grinding concrete, masonry, screed, tile or fibre-cement board releases respirable silica: cut wet or extract at the tool, and wear a P2/N95 respirator at minimum — a nuisance dust mask does not filter it.
- Wet cement and lime burn skin and eyes painlessly until the damage is done: waterproof gloves to EN 374, safety glasses whenever the mix can splash, and never kneel in wet mix in permeable trousers.
- Saws, grinders and breakers run above 85 dB, where hearing damage accumulates and does not recover: defenders or plugs for every cut, not just the long ones.
- Breakers and grinders cause permanent nerve damage: limit continuous trigger time, keep hands warm, and stop if fingers tingle or blanch.
- Boards, blocks and bagged material cause most lasting back injuries on small sites: two people or a lifter for full sheets, and never a bag on one shoulder up a ladder.
