MatCalc

Calculate material coverage, conversions, and turf installation needs.

MatCalc is a fast, offline material calculator built for landscapers, contractors, DIYers, and anyone working with bulk materials. Get accurate estimates for coverage, tonnage, cubic yardage, and artificial turf needs — all in one app with no internet connection required.

Coverage calculator

Calculate area and material needs for any project. Choose from 15 shapes — Rectangle, Square, Triangle, Circle, Half Circle, Quarter Circle, Oval, Annulus, Trapezoid, Parallelogram, Rhombus, Pentagon, Hexagon, Octagon, and L-Shape. Enter dimensions in feet and inches for precision. Pick from 12 preloaded materials across rounded rock, angular rock, specialty stone, base materials, and soil and mulch. Results show square footage, cubic feet, tonnage ranges, and cubic yard estimates with settling adjustment.

Gallons to cubic yards converter

Convert US gallons to cubic yards in a single tap. Always rounds up to two decimal places so you never underestimate. Single input, one number out, designed for on-site use.

Turf calculator

Plan artificial turf installations with accurate nail and infill estimates. Enter length and width and get total square footage, perimeter and seam and grid nail counts, number of nail boxes, infill weight in pounds, and number of infill bags. All settings are adjustable — nail spacing, grid spacing, nails per box, infill rate, bag weight, and roll width.

How to calculate cubic yards of gravel

The same workflow handles mulch, soil, sand, and base rock. The settings in MatCalc default to landscape-grade material; adjust depth and material density for your specific project.

  1. Pick a shape. Open the Coverage tab and tap the shape that matches your area — rectangle, circle, L-shape, hexagon, and 11 more.
  2. Enter dimensions in feet and inches. MatCalc accepts both, so a 12′6″ bed doesn’t need decimal math.
  3. Set depth. Driveway gravel usually wants 4″; decorative mulch 2″–3″; base rock 6″.
  4. Pick a material. Twelve preloaded materials cover rounded rock, angular rock, specialty stone, base, and soil/mulch — or add your own with a custom coverage rate.
  5. Read the results. Square footage, cubic feet, cubic yards, and a tonnage range. MatCalc rounds up by default and applies a settling adjustment so you don’t come up short on delivery day.

Need to convert a delivery quote in gallons to cubic yards? The Gallons-to-Cubic-Yards converter does it in a single tap, always rounded up to two decimal places.

Frequently asked

Does MatCalc work without internet?

Yes — fully offline. There’s no account, no telemetry, and no network calls. Open the app on a job site with no signal and everything still works.

What shapes does the coverage calculator support?

Fifteen: Rectangle, Square, Triangle, Circle, Half Circle, Quarter Circle, Oval, Annulus, Trapezoid, Parallelogram, Rhombus, Pentagon, Hexagon, Octagon, and L-Shape.

Which materials are preloaded?

Twelve materials across rounded rock (pea gravel, river rock), angular rock (crushed stone, drainage gravel), specialty stone (decomposed granite, lava rock), base materials (road base, crushed concrete), and soil and mulch.

Can I add my own materials?

Yes. Add a custom material with a custom coverage rate per cubic yard and it sticks around for the next job.

Does MatCalc handle artificial turf installation?

Yes. The turf calculator returns square footage, perimeter, seam-nail count, grid-nail count, number of nail boxes, infill weight in pounds, and number of infill bags. Nail spacing, grid spacing, nails per box, infill rate, bag weight, and roll width are all adjustable.

Does it account for settling and waste?

Tonnage and cubic-yard estimates include a settling adjustment by default, and rounding always favors over-ordering rather than coming up short.

Is MatCalc free?

Free for closed-alpha testers. Pricing at public launch will be determined before Play Store release.

Available on iOS?

Android only. iOS may follow if there’s clear demand.
