Paint coverage and product orders.
Separate wall surfaces, selected coats, product coverage and whole containers.
Choose the matching calculation
Paint Calculator
Estimate paint containers from measured area, coats and the coverage on your product label. See required paint and purchased surplus.
Exterior Paint Calculator
Combine rectangular facades and triangular gables, then calculate paint containers.
Separate Paint Product Order Calculator
Order distinct finishes or colors separately instead of pooling their incompatible coverage and container sizes.
Mixed Paint Container Purchase Calculator
Find the lowest stated purchase cost using two compatible container sizes for the same coating.
Paintable Trim Profile Surface Calculator
Estimate finish area from the developed exposed profile width, run lengths and separately measured end faces.
Specified Coating Film Volume Calculator
Translate a supplied ordinary decorative coating dry-film thickness and volume solids into theoretical wet coating volume.
Coating Dilution Basis Calculator
Distinguish a percentage of original product from a percentage of final volume.
Measure and check your assumptions
Keep per-coat paint coverage separate from completed-system coverage
Does the product coverage figure already include the specified coats?
Separate theoretical coating film volume from a purchase estimate
Can dry-film thickness replace a product coverage and container calculation?
Apply a material allowance once
Where should an allowance enter a purchase estimate?
Keep paint colors and finishes as separate orders
Which coating quantities may be pooled before container rounding?
Read the denominator in a supplied dilution percentage
Does ten percent mean of original product or of final total?
Include exposed panel edges in a furniture finish estimate
When does two-face panel area still omit a paintable surface?
Use the exposed contour width for painted trim
Why can a moulding’s bounding face width understate its finish area?
When to pool packs across work phases
Should you round each work phase separately or combine an order?
Compare mixed compatible container sizes
When can one large container plus small containers beat an all-large order?
Treat wall openings differently for paint and wallpaper
Why does subtracting opening area not automatically save full wallpaper drops?
Distinguish masking passes from paint coats
How do repeated masking passes affect tape purchasing?
Keep the estimate within scope
Use your measured geometry and already supplied product specifications. Counts and quantities do not select a construction system or establish code compliance.
