How much space does a guinea pig pair need? Measure your setup

Guinea pigs are small, but welfare groups say they need far more room than most pet-shop cages offer. Blue Cross and PDSA both publish minimum sizes for the living area and the run.

Enter your own measurements and see how your set-up compares, drawn to scale. You also get the key housing basics: a solid floor, a hide for every pig, and why one big level beats a tall tower of ramps.
