Pet calculators and size guides
The sizing questions every pet shop and every product page dodges: which crate length for a cavoodle, how big a bed a labrador needs, which harness band for a staffy, how old a ten-year-old kelpie really is. Answered in the units Australians use, on a phone, in the aisle.

Why these, and why centimetres
Almost every pet sizing chart online is American. It measures in inches and pounds, names crate sizes by the inch, and assumes a breed mix that does not match the cavoodles, staffies, kelpies and greyhounds in Australian homes. Every figure here is in centimetres and kilograms, matched to the sizes sold on Amazon Australia, and where welfare is involved it follows RSPCA and Australian Veterinary Association guidance.
Nothing here needs an account, an app or an email address, and none of it sends your figures anywhere. Each tool remembers your last inputs on your own device so it opens where you left it, and every result has a link you can share or bookmark.
