How Much Paint Does a Front Door Need?
A standard front door is 36 inches wide by 80 inches tall — just 20 square feet per side, or 40 square feet total for both sides. At 400 square feet per gallon, one quart (0.25 gallon) is more than enough for two coats on a single door with paint left over for touch-ups.
A double front door has roughly 80 square feet of paintable surface. One quart handles two coats easily with paint remaining. If you are also painting the door frame and surround, budget a second quart.
In litres, one 750ml tin is enough for most front doors. A double door or door plus frame may need a 1 litre tin.

Best Paint for a Front Door
Use exterior gloss or semi-gloss paint specifically formulated for doors. Oil-based alkyd paints give the hardest, most durable finish but take longer to dry and require solvent cleanup. Quality exterior latex paints (such as Benjamin Moore Aura Grand Entrance or Sherwin-Williams Emerald Exterior) are easier to apply and clean up but equally durable when properly applied.
Avoid standard exterior wall paint on a front door — it is not formulated to withstand the constant opening, closing, touching, and weather exposure that a front door receives.
Tips for Painting a Front Door
Remove the door from its hinges if possible — painting flat on sawhorses gives a far cleaner result than painting in place.
Remove all hardware including the handle, knocker, letterbox, and hinges before painting. Masking hardware rarely gives a clean result.
Sand lightly with 220-grit before painting to give the surface tooth for adhesion. Wipe clean with a tack cloth before priming.
Paint in this order: panels first, then rails, then stiles (vertical sections), then edges. This gives the cleanest overlapping joins.
Allow 4 to 6 hours between coats for exterior door paint. Do not rehang the door for at least 24 hours to prevent sticking.
