How to use the brand chart
The table on this page is a planning range for interior latex on smooth primed drywall. Click a brand for a 12×12 worked example, then enter your room size in the calculator with the Coverage number from that specific can.
We are an independent calculator — not a manufacturer colour tool, not a store affiliate page. See the disclaimer under the table.
12×12 room (any of these brands)
384 sq ft of walls × two coats = 768 sq ft to cover. At 400 sq ft/gallon that is 1.9 gallons (buy 2). At 350 sq ft/gallon that is 2.2 gallons (buy 3). Texture, primer, and colour change are why two brands with the same label rate still need different carts.
