Most Common Aquarium Sizes Chart (Dimensions And Weight)

by

I’ve often been found walking around my local fish store thinking how heavy those large display aquariums weigh? This got me thinking that many of you might be wondering the same thing.

So I did some research to find out some common sizes and weights of aquariums and I put it all together in a neat little chart so you have something to reference when you are about to pick up your first aquarium.

Here’s the chart;

The above information is for most standard glass aquarium sizes and weights. If you are considering an acrylic tank, they are available in many of the same sizes, they will just weigh a little less.

One thing to keep in mind is that as glass aquariums get larger the thickness of the glass increases, which is why the weight of the aquarium can get very heavy.

Acrylic on the other hand is lighter and stronger than glass which is why some go for an acrylic aquarium when they get to the larger sizes. However, it’s important to note that Acrylic scratches very easily.
