Mouse Housing tools: what they help with
These calculators size your mouse's living space: the minimum and recommended dimensions, how much bedding or substrate to buy and what fits in the space you have. Too little space is one of the most common welfare problems in pets. The right size gives a mouse room to move, rest and behave normally.
What to know about housing and enclosure size for mice
Mice need a secure tank or narrow-bar cage with deep bedding for burrowing and plenty of climbing height. Females live well in groups; males usually must be housed alone to avoid fighting. Target humidity is around 40-60%.

Treat the minimum as the floor, not the goal. Bigger is almost always better, especially for active or social species.
