How big should a hamster cage be — and how much bedding?
Check floor area against Syrian/dwarf minimums and estimate bedding liters from cage size and depth.
Quick answer
Hamsters dig: floor area and deep bedding matter more than fancy tubes. Welfare-minded keepers aim for large continuous floors — often cited around 75×40 cm or more for a Syrian (about 3000+ cm²), with dwarfs still needing generous space. Bedding volume is simply floor area × depth: 20–40 cm of paper or aspen-style substrate is common so they can burrow.

Welfare-minded minimums often cite ~3000 cm² continuous floor for Syrians (e.g. ~75×40 cm) and still-large floors for dwarfs, with deep bedding to dig. Liters = L×W×depth in meters × 1000. Avoid dusty softwood shavings and nesting fluff that tangles. Not veterinary advice.
How it works
Enter your cage length and width to see if you meet a practical minimum, then set bedding depth to get liters (and roughly how many 10 L or 25 L packs). Wire-only tiny cages fail the dig test even if the label says “hamster.” Not a veterinary diagnosis — upgrade space whenever you can.
Frequently asked questions
What is the minimum cage size for a Syrian hamster?+
Many welfare guides treat ~3000 cm² of unbroken floor (e.g. about 75×40 cm) as a practical minimum, with deeper bedding. Bigger is better. Dwarf hamsters still need large floors — do not house them in tiny modules.
How much bedding do I need?+
Liters ≈ length(m) × width(m) × depth(m) × 1000. Example: 80×40 cm with 30 cm depth ≈ 96 L — several large bags. Spot-clean and top up; full changes are rarer with deep clean sections.
Which bedding is safe?+
Paper-based and kiln-dried aspen-style products are popular. Avoid dusty pine/cedar oils and fluffy cotton-like nesting that can tangle limbs. Check packaging for hamster use.
Can two hamsters share a cage?+
Syrians are solitary as adults. Some dwarf species can cohabit only with care and space — fighting is common. When in doubt, one hamster per enclosure.
