How Much Paint to Order



Not ordering enough paint for your decorating project can be very frustrating, but over ordering will mean you're left with items you don't need. You can minimize the chances of this happening by using our convenient paint calculator. While our advice is for guidance only, we would strongly recommend that you always check with your decorator before ordering or email customerservices@farrow-ball.com for further advice or assistance. Please note that we do not take doors, windows and alcoves into consideration when making our calculations.

Please also take into account the nature of the surface which you are painting beforehand. Porous walls are likely to require extra coats and vast colour transformations (i.e. white to black or black to white) are also likely to require a third coat. You can minimize the chance of this by using the correct undercoat.

The table below offers a guide to the maximum coverage for all our paint finishes. Coverage is dependent on thickness of application and surface. All product pages contain an interactive paint calculator to help you choose the right amount - please note this calculator is only suitable for calculating paint for walls only.
