Paint Calculator – How Much Paint Do I Need?

Getting the right amount of paint depends on a great many things, such as what colour you are covering up or how high the room is. Understanding how much paint you need is not an exact science – and our calculations don’t discount doors and windows but as a guideline, we would suggest the following quantities for your walls. Please note that our calculator allows for two top coats and rounds up the total number of litres you need to the closest tin size. So, for example, if your room requires in total 6.5L of paint, it will round up to 7.5L (one 5L tin and one 2.5L tin). This way you can be sure you won’t run out of paint for your room:
