Texture material needed

1.32 gal

Check your inputs

Coverage rate varies significantly by texture type (orange peel, knockdown, popcorn) and application equipment — confirm your specific product's rated coverage from its technical data sheet.

With the figures above, the texture material needed comes to 5. The method behind this is well established, though site conditions and material batches will move it somewhat. This is calculated for United States and cites IRC 2024. Building in another market? Change the selector above so the units and code reference follow.

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.

Preliminary estimate, not certified engineering. This tool produces an indicative quantity calculation for planning purposes only — it is not a certified structural analysis, a guaranteed material takeoff, or a substitute for building department approval. Always verify measurements on-site and have a licensed contractor or structural engineer review any load-bearing, code-sensitive, or safety-critical work before purchasing materials or starting construction. Spotted an arithmetic or standards error? Report it to contact@craftquantities.com with your inputs — confirmed fixes become pinned regression tests.

Frequently asked questions

Why does texture coverage vary so much between products?
Different texture patterns require different amounts of material — a heavier knockdown or popcorn texture typically uses more material per square meter than a light orange-peel finish, and spray gun setup (nozzle size, air pressure, hopper technique) also changes how much material lands on the wall versus overspray.
Where do I find the coverage rate for my texture product?
Check the manufacturer's technical data sheet for the specific texture compound — it will list a rated coverage area per unit volume for the intended application method, which should be used here instead of a generic assumption.
Does this account for multiple coats or touch-ups?
No — this calculates material for a single texture application over the given area. Add extra material separately if your job requires multiple passes, heavier texture buildup, or touch-up coverage.
