Owning a guinea pig is incredibly rewarding and a great source of companionship. Guinea pigs are the most popular rodents kept as a pet and yet their available housing is relatively smaller to keep more than one guinea pig.
You can find a variety of options for guinea pig cage size at the pet shop, however, you need to provide them with an ample space to roam and exercise and separate spaces for food, water, sleep, and bathroom area.
They love to socialize and spend time with human families and other guinea pigs. Being a social creature, owners keep them with several other guinea pigs. Thus, housing them in a smaller space can result in unhealthy guinea pigs.
Study shows, most of the available sizes in the market are generally undersized or designed for one pig. So, what should be the right guinea pig cage size?
Here is an extensive guideline that you should follow before making a sweet home for your loved pet.
Guinea Pig Cage Size – What is the right size?
Unlike other animals, guinea pigs rely on floor area rather than digging, climbing, and burrowing. However, low height platforms and ramps provide a variety while playing and exercising.
You can follow the below guidelines before planning to design a guinea pigs cage:
For One Guinea Pig:

For one guinea pig, you must consider having a minimum of 7.5 square feet, that is 30” x 36”, cage size but bigger is better, and choosing 42” x 24” size of the cage will be a wise option.
Your guinea pig cage should be at least 12 to 18 inches tall in addition to 7.5 square feet space for your guinea pig to run around in.
For Two Guinea Pigs:

New guinea pig owners are advised to have them in a pair to keep each other company and adding up 2 to 4 square feet of space per guinea pig is a rule to always follow.
Therefore, using this rule, a cage for two guinea pigs should be anywhere from 9 to 11 square feet of space. Keeping the same height from 12 to 18 inches, 30” x 50” is a good size for a pair of either male, or female, or one male and one female (one fixed in one cage).
For Three Guinea Pigs:

Having a 15 square feet cage size is ideal for three guinea pigs, however, 13 square feet should be the minimum cage size, that is, 30” x 62”.
The housing of three guinea pigs could be a little trickier thing. Housing only one male guinea pig in a mixed herd can avoid conflict. You should always house one male with two other female guinea pigs, or three female guinea pigs, but you should not ever house one female guinea pig with two other male.
For more than three guinea pigs, you should consider following the above rule of increasing two to four square feet of space per guinea pig.
