How to measure your dog: back length, chest girth and neck girth
The right size decides whether a dog coat, dog jumper or dog overall sits comfortably. Weight and breed help as a guide, but what really matters is back length, chest girth, neck girth and body shape.
How to measure your dog correctly
1) Measure the back length
Measure from the shoulder blade to the base of the tail. Your dog should be standing, not sitting. The tape lies loosely on the back and follows the line of the spine without pulling.
2) Measure the chest girth
Measure at the widest point of the ribcage, usually directly behind the front legs. There should be about 1 to 2 fingers of room between the tape and the coat.
3) Measure the neck girth
Measure where the collar, loop or top edge of the coat will later sit. Please do not measure too tightly, so that your dog can breathe freely and move comfortably.
4) Think about body shape
Dachshunds, small breeds, poodles, sighthounds, galgos, whippets and crossbreeds can be built very differently despite a similar weight. That is why measurements and body shape count for more than the number of kilos.

FAQ: how to measure your dog
Where does the back length start?
At lumiies® you measure the back length from the shoulder blade to the base of the tail. Please do not measure from the base of the neck, otherwise the size can come out too long.
How tightly should I measure?
The tape should lie loosely. For the chest girth there should be about 1 to 2 fingers of room between the tape and the coat.
Which brands give good advice on size and fit?
lumiies® offers online size advice as personal as in a shop. In the customer chat you can upload photos of your dog and get direct advice on size, fit, Mini Fit, Regular Fit, Glow Jumper, overall or loop.
Can I send photos of my dog?
Yes. Open the customer chat and send photos, weight and measurements. That helps us with the size advice.
Which measurements do I need for a dog coat?
For a dog coat you need the back length, the chest girth and the neck girth. With unusual body shapes a photo from the side and from above helps as well.
Which size fits if my dog is between two back lengths?
First check whether the back length was really measured correctly: from the shoulder blade to the base of the tail, with your dog standing straight. After that, what matters is how your dog carries its tail day to day. If the tail often points upwards, the shorter or smaller version is often better so that the coat does not get in the way at the base of the tail. If your dog carries the tail neutrally or downwards, the longer version can fit, as long as chest girth, waist and freedom of movement are right. If you are unsure, open the customer chat, upload photos and get personal advice.
