You are watching: Weight of a gallon of paint

Planning to freshen up your walls by repainting them? Eyeing to conduct a creative art project that will demonstrate your artistic skills?

Before you start any of these, buying gallons of paint is the first thing you’ll need to do.

However, this is also where the problem starts. While it’s easy to choose what color you’ll be using and what brand you’ll be purchasing, knowing how much paint you’ll be needing could present a challenge.

You must also take the weight of the paint into account, depending on how you plan to transport the paint you need.

In this article, we will look at both sides of the equation: how to determine how much paint you need, and how much that paint will weigh.


Normally, paint is measured in gallons. In local stores, you can usually purchase them in varying sizes, with one gallon and five gallons being the most common you are likely to see.

However, the weight of the paint depends entirely on what type of paint it is.

In order to determine the weight of paint, you need to know the specific gravity of that particular type of paint. Specific gravity is a comparison of material to water. Some paint manufacturers list the specific gravity of their paint on the label.

If they’ve done so, you can then find the weight by multiplying by 8.345 to find pounds per gallon.

If you don’t feel like doing the math, though, here are some of the most common paint types and their weights:

Latex Paint: 11.3 pounds per gallonAcrylic Paint: 11-12 pounds per gallonOil-Based Paint: 6.7 pounds per gallonEnamel Paint: 11 pounds per gallon

Of course, all of these measurements still depend on the brand, these are simply estimates.
