Sod Calculator
Calculate the number of 10-square-foot sod rolls required for a rectangular lawn area.
Topsoil Calculator
Estimate the cubic yards of topsoil needed based on project area and desired installation depth.
Mulch Calculator
Calculate mulch for garden beds, tree rings and landscaped areas. A depth of approximately three inches is commonly used.
Stone Calculator
Estimate cubic yards and approximate metric tonnes for decorative stone, clear stone or granular base material.
Square Footage Calculator
Calculate the area of a rectangular lawn, garden bed, patio or landscape section.
Cuts, curves, settling and uneven depth can increase the final quantity.
Small depth changes can significantly affect cubic-yard requirements.

Material Ordering Recommendation
Always Account for Settlement & Compaction
We recommend ordering at least 15% extra material. Topsoil, mulch, sand and stone naturally settle and compact during installation and over time. Ordering a little extra helps maintain the intended finished depth and provides an allowance for uneven grades, compaction and minor measurement differences.
How the calculations work
Simple Measurements, Practical Estimates
These tools use standard area and volume formulas. Results are rounded to make ordering easier but do not replace an on-site assessment.
Square footage
Length in feet multiplied by width in feet equals total square feet.
Cubic yards
Square feet multiplied by depth in inches, divided by 324, equals cubic yards.
Sod rolls
Adjusted square footage divided by 10 equals the number of Sod Kings ten-square-foot rolls.
Calculator questions
Frequently Asked Questions
Should I order exactly what the calculator shows?
Order quantities are generally rounded upward. Additional material
may be required for cuts, irregular shapes, settling, compaction,
uneven grades or measurement errors.
How many square feet does one sod roll cover?
The sod calculator assumes one roll covers 10 square feet. Confirm
the current product dimensions before ordering.
How much area does one cubic yard cover?
One cubic yard covers approximately 108 square feet at three inches
deep, 162 square feet at two inches deep or 324 square feet at one
inch deep.
Why is the stone weight only approximate?
Aggregate weight varies by product, particle size, moisture content,
compaction and supplier specifications. The calculator uses general
planning densities rather than guaranteed product weights.
Can Sod Kings confirm my measurements?
Installation estimates may include a project review or site
assessment. Material-only customers remain responsible for confirming
measurements and quantities before ordering.
