Artificial Grass Sand Calculator
Sand infill helps synthetic turf stay stable, keeps fibers upright, and improves durability. Too little infill feels loose and wears faster; too much can hide the pile. This tool estimates infill volume and weight from turf area and infill depth (same as area = length × width, volume = area × depth).

Infill sand
Typical bulk density for rounded infill sand is about 1600 kg/m³—adjust if your infill product specifies a different value.

How this calculator works
Steps:
- Area = length × width of the installed turf (enter total area if you already know it)
- Volume = area × infill depth
- Volume in m³, ft³, or yd³
- Weight = volume × density (default ≈ 1600 kg/m³)
- Bags = kilograms ÷ bag size, rounded up (default 50 kg)
Recommended sand infill depth
Depth depends on yarn, pile height, and traffic (always follow the turf manufacturer):
- 10–15 mm — lighter residential use
- 15–25 mm — common residential and landscaping
- 25–40 mm — higher traffic or some sports-style systems
Why sand infill is important
- Stability — ballast to reduce movement
- Durability — less premature wear in many designs
- Support — helps fibers stand for appearance and feel
- Weight — reduces lifting and wrinkling
Under-infilled turf often mats and shifts sooner than properly dressed systems.
Where this calculator is used
- Artificial lawns
- Residential and commercial landscaping
- Sports and practice fields
- Playground or daycare turf
- Pet-friendly installations
Example calculation
Area:
- Length 8 m, width 5 m → area 40 m²
- Infill depth 20 mm (0.02 m)
Step 1 — Area = 8 × 5 = 40 m²
Step 2 — Volume = 40 × 0.02 = 0.8 m³
At 1600 kg/m³: weight ≈ 1280 kg (~1.28 t). At 50 kg per bag: 26 bags when rounded up.
Choosing the right sand
Not every sand grade is meant for turf:
- Silica sand — widely used for stability and grading control
- Kiln-dried sand — flows and spreads easily for brush-in
- Washed sand — lower fines and dust in many products
Avoid high clay or dusty fills that can clump or compact poorly—use the turf supplier’s specified grain size.
Product-specific rates
Turf manufacturers often publish kg per m² or pounds per square foot for each product line. Use this calculator as a cross-check, then align final orders with the data sheet for your exact roll.
Common mistakes to avoid
- Too little infill — loose feel and early fiber collapse
- Overfilling — blades look buried or “sandy”
- Wrong sand type — poor drainage or compaction
- Uneven spread — visible humps and thin spots
Practical tips
- Spread with a drop spreader, broadcaster, or careful shoveling
- Brush between lifts to work sand into the thatch
- Apply in layers rather than one dump
- Add 5–10% extra for spillage and adjustments
Frequently asked questions
How much sand do I need for artificial grass?
It depends on area and infill depth; many residential jobs fall near 10–25 mm in planning guides, but your product sheet is authoritative.
Can I install artificial grass without sand?
Only if the system is designed for little or no infill. For sand-dressed turf, skipping infill usually hurts performance—follow the manufacturer.
What is the best sand for turf infill?
Silica or kiln-dried sand matched to the turf spec is common; grain size and cleanliness matter more than the marketing name alone.
Does sand infill need maintenance?
Yes—brush, groom, and top up infill as needed over time.
