How Much Does A Gallon Of Paint Weigh? (Answered By Type)

If you are starting a home renovation or a DIY project, you might be asking yourself, "How much does a gallon of paint weigh?" 

The precise weight of a gallon of paint will depend on what type of paint you are using and the brand name.  

Knowing how much your paint weighs will help you determine how much you might need to finish a particular project.  

A gallon of paint weighs between 6 to 12 pounds, depending on what type of paint you have and what brand of paint you are using. The best way to calculate the weight is by looking at the product information found on the bucket or website if you are purchasing online. You can also ask someone at the hardware store for advice on how to calculate it.  

Paint is usually measured in pounds. You can convert the gallon to pounds by knowing the density of the liquid. This can still be complicated, though, and most people choose to use an online calculator for help.  

A gallon of latex paint will usually weigh 11.3 pounds and will cover about 400 square feet. Determining how much a bucket of paint will weigh depends on the size of the bucket and what kind of paint is it in.

Different Types Of Paints & How It Affects The Weight 

The type of paint you choose will affect how much your gallon weighs. For example, oil-based, enamel, latex, and acrylic paints change the weight and density of paint. Some pigments might also be mixed, which can change the weight of the paint. The paint weight varies because of how the paint is made and whether it is oil or water-based.

Acrylic Paint  

Acrylic is a water-based paint that’s similar to latex paint. Water-based paint is always heavier than oil-based paint, so acrylic paint will always weigh more. Acrylic paint is often mixed with latex paint and then sold in gallon sizes. If you see acrylic paint not mixed with latex, it’s probably only sold in ounces.  

Latex Paint  

Latex paint is also water-based, with an average gallon weight of around 11.3 pounds. Latex paint is often the most popular choice for homes because it’s durable and much easier to clean up than oil-based paints.  

Enamel Paint  

The weight of enamel paint is often harder to measure because it can be acrylic or oil-based. The density and weight will also depend on the brand you are buying. If you aren’t sure if your paint is oil-based or acrylic, you can multiply the density by the volume.  

Oil Based Paint  

Since oil has a lower density than water, the oil-based weight will weigh less than other types of paint that are water-based. Some oil paint is also dry oil-based. This has an even lighter weight and is often used for crafts rather than home painting or fixture painting.  

Paint Standard Measurement 

Most paints that are sold in gallons are in one gallon or five gallon containers. The gallon is a consistent measurement because it's not affected by the liquid you are measuring—a gallon of water for insistence. The gallon measurement is the standard measurement for all paint sold in the United States.  

In other countries, though, there are different measurements for gallons, and the gallons might be bigger or smaller than the US gallon.  

  • Imperial Gallon
    This is a measurement used by people living in Canada and The United Kingdom. Parts of the Caribbean also use this Imperial Gallon. In liters, the measurement is about 4.5. 
  • The US Gallon  
    The US gallon is the standard measurement for a gallon of paint. Compared to the Imperial Gallon, it is smaller at 3.8 liters.  
  • US Dry Gallon 
    This form of measurement is rare and probably not something you will encounter when looking for and buying paint. It measures about 4.4 liters and is specifically used to measure the weight of a liquid when it becomes a solid.
