Sand Calculator: The Complete Guide to Estimating Tons, Cubic Yards, and Cost
Sand is one of the most commonly used materials in construction and landscaping — from paver bases and concrete mixing to sandboxes and beach volleyball courts. Getting the quantity right prevents costly shortages and overages. Sand is heavy (a cubic yard weighs about 2,700 lbs) and expensive to deliver, so accurate calculations save both money and headaches.
The Sand Formula
Volume (cu ft) = Length (ft) × Width (ft) × Depth (in) ÷ 12
Cubic Yards = Volume (cu ft) ÷ 27
Tons = Cubic Yards × Density (typically 1.35 t/yd³)
Pounds = Tons × 2,000
50 lb Bags = Pounds ÷ 50
Quick Rule: 1 cu yd covers ~162 sq ft at 2" deep
Worked Example — Paver Leveling Sand
Patio: 16 × 12 ft, 1 inch deep leveling sand
Volume: 16 × 12 × 1 ÷ 12 = 16 cu ft
Cubic yards: 16 ÷ 27 = 0.59 cu yd
Tons: 0.59 × 1.35 =
0.80 tons (1,600 lbs)50 lb bags: 1,600 ÷ 50 =
32 bagsBulk cost: 0.59 × $35 =
$21 (vs $128-$192 in bags!)
Sand Types and Uses
| Type | Weight (tons/yd³) | Cost/yd³ | Best For |
|---|
| Concrete Sand (Sharp) | 1.35 | $30-$45 | Paver bedding, concrete mix, drainage |
| Play Sand | 1.30 | $25-$40 | Sandboxes, play areas, volleyball |
| Mason Sand | 1.35 | $35-$50 | Mortar mixing, final grading, pool bases |
| Fill Sand | 1.40 | $15-$30 | Backfill, grading, pipe bedding |
| Decomposed Granite | 1.50 | $35-$55 | Paths, driveways, xeriscaping |
Pro Tip — Bulk vs. Bags
Bulk sand costs $25-$50 per cubic yard. Bagged sand costs $4-$6 per 50 lb bag, which equals $216-$324 per cubic yard — 4 to 10 times more expensive. For any project needing more than 0.5 cubic yards, buy bulk. Most landscape suppliers deliver for $50-$150. If you have a pickup truck, you can haul about 0.5-1 cubic yard per trip (1,350-2,700 lbs — check your truck's payload rating).
Critical — Use the Right Sand Type
Using the wrong sand type causes project failures. Never use play sand (too fine, shifts under load) as paver bedding — use coarse concrete sand. Never use construction sand in children's sandboxes — it may contain silica dust and contaminants. Don't use regular sand for paver joints — use polymeric sand. Mason sand is too fine for drainage applications. Fill sand is the cheapest but not suitable for visible surfaces.
