How to Measure Your Pet (Harness, Crate, Cat Door)
Chest girth, neck, length, three measurements for any pet product order. Plus the cat-door rule of "shoulder width + 2 cm."
Pet harnesses are returned more often than human clothes, same fit issue, smaller animal. iPhone makes the three critical measurements quick (when the pet cooperates).
为什么测量
- Harness fit (chest girth is the key number)
- Cat/dog door width
- Crate sizing for transport
- Custom bed dimensions
需要准备
- iPhone with Ruler AR
- Length mode (pet may not stand still, Touch mode helps)
分步操作
- Chest girth. Behind the front legs, around the widest part of the rib cage. Length mode: hold one finger at the start, tap on the phone at the wrap-around point.
- Neck circumference. Around the base of the neck where a collar sits.
- Body length. Base of neck (where collar sits) to base of tail. For harness back-piece sizing.
- Door / opening width. For cat doors: shoulder width + 2-3 cm. For dog doors: chest girth ÷ π gives the diameter; add 5-10% safety.
小贴士
- Measure when the pet is relaxed/calm, stress measurements are misleading
- Long-haired breeds: measure under the fur to get the actual body dimension
常见错误
- Using the size charts without measuring, breeds vary wildly within "small/medium/large"
- Forgetting to measure when wearing a winter coat or vest

What's the most important pet harness measurement?
Chest girth. Get it right and the harness fits. Get it wrong and you'll return.
