Measurement accuracy
Results depend on the accuracy of the values entered. Measure the real project area and keep units consistent. Recheck unusual shapes, openings, slopes and repeated sections before ordering materials.
Material and product variation
Coverage, density, package size, board dimensions, tile yield, paint spread rate and other product characteristics vary by manufacturer and product. Use the specifications printed on the product or supplied by the manufacturer whenever possible.
Waste and purchase quantities
Waste allowances are planning assumptions, not universal rules. Complex layouts, patterns, breakage, cuts, defects and installation experience can increase the amount required. Purchase quantities may also be affected by how a supplier packages and sells the material.
Cost estimates
Prices entered into DIYGauge are user-controlled planning values. Taxes, delivery, minimum-order charges, labor, disposal, permits, equipment and regional price differences may not be included unless the calculator specifically provides an input for them.
Safety, structure and local codes
Do not rely on a DIYGauge result as approval for structural capacity, electrical or plumbing design, fire safety, accessibility, permitting or code compliance. Verify regulated and safety-critical work with the appropriate qualified professional and local authority.
Final verification
Before purchasing large quantities or starting work, compare the DIYGauge result with manufacturer instructions, supplier packaging, project drawings and local requirements.
