11 Recommended Hamster Cages To Choose From (Both DIY and Purchased) 2021

When considering the best hamster cages, you need to note that a hamster requires space to roam and play/exercise. Limited space will make it unhappy or snappy and it can bite.

Best Hamster Cage Minimum cage dimensions for a Syrian Hamster and dwarf hamsters:

Different sources have given different dimensions. However, the minimum floor L x W should be 450sq inches.

  • (30” L by 16” W by 16”H) that is (76cm L by 40cm W by 40cm H)
  • (40” L by 16” W by 16”H) that is (100cm L by 40cm W by 40cm H)

Bigger is always better!!!

Tight Budget?

If you are working on a tight budget, the cheapest and best hamster cages can be made of a plastic bottom and a wire canopy. An advantage of these kind of cages is that they are easy to keep clean and have a variety of sizes.

NB: Some cages come with accessories and some don’t. DO NOT get round cages, hamsters love corners. Also, make sure the cage floor is solid NOT wired.

Here are the best hamster cages based on owners and experts.  It is up to you to pick the one that works for you (budget-wise, space-wise, appearance-wise etc.) as they are all good for your hamster.



tip this on its side and take out the shelves. You will need to get a lid that must be meshed to prevent chances of hamster escape or some predator getting into the cage. The mesh also allows for proper ventilation.

See setting up videos. (You will get to see how this cage looks like in your home setting)

Bin Cages

Hamster Bin Cages

Most people do not recommend these claiming poor ventilation and the likelihood of your hamster chewing a hole and escaping. Some people also say that your hamster will not be visible through the plastic compared to glass. That being said, it is up to you.

If you go the Bin Cage way, make sure the bin cage is at least 30” length by 20” width by 16” height. This really matters for fitting accessories and offering enough space for your hamster. We know getting a large bin can be tasking. We found this one that is slightly lower than 450 sq. inches. It is 432 sq. inches and can work.


For ventilation, there are different options you can go with, which are, removing the lid and placing a tight-mesh wire shelving like the image above or making a mesh wire top and mesh wire window. Sometimes the window is not recommended. Also, see video below.

    I would like to very kindly point out that the tank should be a 40 gallon breeder as it has more floorspace than a 40 gallon long. The 40 gallon long is actually just below minimum floor space. 🙂

    1. Srob says:

      Not true. 40L is about 576 square inches

      1. chase says:

        Actually, a 40 gallon breeder does have more space – 643 square inches.

  2. Emma Dickinson says:

    I would like to point out that the IKEA detolf is equivalent to a 90 gallon and is only 60$ in the US so it is actually more convenient than the 40 gallon breeder.Also my female short haired Syrian was in a 40 gallon breeder, and when I upgraded her she really enjoyed it.
