By measuring the bag’s volume after manually flattening it on the ground.This is the most accurate methodology for calculating the needed amount but most brands don’t list volume By using the gravel’s volume if it’s listed on the bag it comes in.This is the most generalized method and is used most of the time Generally speaking, there are three main ways you can calculate how much gravel an aquarium needs: So with that out of the way, we can move to the formulas. Multiply the dimensions to find the tank’s bottom footprint in square inches or centimeters and write the answer down.Write the fish tank’s length and width down.In it, I’ve listed the measurements of all the standard-shaped tanks and their gallon capacities along with the most popular irregularly-shaped ones.įind the tank that you have or want to get and check out its width and length.įrom here on there are two steps you need to take: To learn the proportions of a tank you can either grab a ruler and measure them or you can use my resource page about fish tank dimensions.
