Dubai is really famous around the world for its style and their beautiful interiors. And since the city is so stylish, it has beautiful skyscrapers plus buildings, the interiors are designed in a unique way in those buildings. Beautiful aquariums are one thing among many that add to the interior’s look. However, having an aquarium isn’t just about buying a tank and filling it up with water, it’s about knowing the volume, the weight, and if it’s actually gonna fit in your room, along with other stuff like decoration.

I’m pretty sure you would like to have an aquarium that fits perfectly in your space and doesn’t cause a flood because you put it on a weak table. But that centerpiece can turn into a disaster very quickly if you don’t measure it the right way. And nobody wants that in their living room.

You must have landed here searching “how to measure aquarium size.”  The guide we’ve brought you today is to help you understand exactly what you need to do. BPK tops the list when it comes to helping you, and that’s what we’re gonna do today as well.

Why Measuring is Actually Important 

Measuring the aquarium isn’t only about doing the math, it’s to find the complete solution for your aquarium design needs. Anybody could make the mistake of picking the wrong filter because its size was too small, but that’d make your fish suffer right? That’s why knowing the right size is important. Also, medicines and chemicals are used based on the volume of the tank so that’s another reason to know this. If you put in more medicine in the tank than needed, you’d be putting your fish in a lot of danger. It could kill your fish. Knowing your aquarium’s size is very important no matter if you have a small one or a big tank.

1. The Basic Formula: No Rocket Science 

The most important and basic part of measuring is knowing the length, width, and height of the tank. 

Rectangular Tanks

The tanks you’d get would mostly be rectangles. To know the volume, you just gotta get a measuring tape and measure the length from one side to the other. You can measure the width from the front to the back. And for the height, from top to bottom. Once you have these 3 measurements, just use the basic length x width x height formula for volume. If your measurements were in cms, divide it by 1000 to get the volume in litres. But this is the volume from the outside, the glass is thick and the water inside will be lesser than what you calculated.

2. Why Volume Matters for Fish 

People ask how to measure aquarium size because they want to know how many fish they can put in. 

The One Inch Rule?

If you’ve been into keeping fish as pets or just owning them for whatever reason, you must’ve heard of "one inch of fish per gallon." Sorry to burst your bubble but that is not accurate since it's old advice. A bigger fish obviously will produce much more waste than a smaller one, so knowing the volume will help you figure out the stocking. Your tank can get dirty real fast and require cleaning more often if you get this wrong. You can have more fish in a 200 liter tank than in a 50 liter tank.

3. Weight: The Hidden Danger 

Water is heavy. Like, really heavy. 

One Liter = One Kilogram

If you have a 300 liter tank, that means that just the water weighs 300 kg!! And then you have the glass which is mostly heavy too, the rocks, the sand, and the stand. All this can add up to your total weight being around 400 to 500 kgs. You need to know how to measure aquarium size so you can know if your floor or cabinet can bear that much weight. Putting a heavy tank on a shelf that can’t hold it will make it collapse and you definitely don’t wanna clean that mess up.

4. Cylinder Tanks

Rectangular tanks are very common but not everyone has those only, Dubai has an immense variety of style and you’d see curved tanks a lot.

Cylinder Tanks

Measuring the volume for curved tanks is of course different. You need to know the radius which is half of the diameter of the tank and the height. Use those measurements to calculate the volume by the formula pi multiplied by the square of the radius multiplied by the height (pi = 3.147.) That’s a little difficult to calculate but if you ask the seller, they’d save you time by telling you the volume straight up or just ask us at BPK!!

5. Accounting for Decor

Calculating the volume of an aquarium like we suggested above means that you’re getting the total volume for an empty box, but you’re of course gonna put stuff inside it. 

Displacement

Sand, Rocks, Driftwood, plus other decoration pieces take up space. If you’ve got a 100 liter tank you’d probably fill it up with around 20 kg of rocks and other stuff, which leaves you with 80 liters of water. This is important when you are putting medicine inside the water so always estimate lower than the total volume to be on the safe side.

6. Filtration and Heating 

Equipment for the aquarium is made for specific sizes. For example:

Filters

You would see “For up to 200 liters” on a box of filters but if you don’t know the size you could get one that would be too weak. This will lead to your water being dirty and the fish being sick.

Heaters

It’s the same for heaters. About 1 watt is needed for 1 liter, so if you have a 100 liter tank, you need a 100 watt heater. Say that you didn’t know this and you got a 50 watt heater, this’ll make your fish get stressed since the water won’t be warm enough for them.

So, What Are Your Choices Finally? 

Measuring can surely be a bit of work, you gotta find the tape, do the math, check the glass thickness, plus figure out the weight; all this takes a lot of time. But you don’t have to do it alone.

FAQs

How do I know what size my aquarium is?

You can grab a measuring tape and measure the length, the width, and the height. Then use the L x W x H formula to get the volume in centimeters and divide that by 1000 for your answer in liters.

How to measure aquarium size in gallons?

You can do this by measuring the dimensions in inches, multiply them , and then divide them by 231 to get your answer in gallons.

Does the glass thickness matter?

The glass thickness matters for sure, the volume you measure from outside includes the thickness of the glass. If the glass is thick the volume inside will be lesser, so for better accuracy, you can take the measurements from inside.

How to measure aquarium size for a cylindrical tank?

You can do this easily by measuring the diameter from inside and the height too. Divide the diameter by 2 to get the radius then use the formula pi x squared radius x height. An easier way  would be asking the seller!!

Why is my tank volume less than the box says?

Manufacturers write down the total volume based on the measurements from outside. For better accuracy, you can take measurements from inside. Also, adding sand, rocks, or other decoration pieces means that even less water will be required.

Do I need to measure for a heater?

Yes, of course. You need 1 watt for 1 liter of water, therefore knowing the volume is important to keep the temperature right.
