How to Measure Your Cat for Clothes: Dolly’s No-Nonsense Guide

# How to Measure Your Cat for Clothes

Hello, I am Dolly. I am a Sphynx, a professional nap strategist, and the only person in this household qualified to decide whether a jumper is cosy or an insult. Before you order cat clothes, get the tape measure. Your cat may be offended. This is temporary. A bad fit lasts much longer.

The useful numbers are chest girth, back length, and sometimes neck girth. Measure your own cat while they are standing naturally, then use the size chart on the exact product page. Breed names, colours and hopeful guessing are charming. They are not measurements.

The three measurements that actually matter

### 1. Chest girth

Wrap a soft tape measure around the widest part of the chest, just behind the front legs. Keep it snug, not tight. You should be able to slide two fingers under the tape. If the chest is too tight, your cat cannot move comfortably. If it is too loose, you have bought a tiny draft tunnel.

### 2. Back length

Measure from the base of the neck, where a collar would sit, to the base of the tail. Keep your cat standing in their ordinary posture. Do not measure while they are curled into a croissant or pretending to be liquid. Those are advanced poses.

### 3. Neck girth, when the product chart asks for it

Measure around the base of the neck and leave a little ease. Again: two fingers should fit under the tape. A good garment should sit comfortably without crowding the neck or restricting normal movement.

Dolly's fitted-dress example

This is not a measuring video. It is Dolly sitting there looking pretty in her dress, which is possible because someone did the measuring properly first. Dolly's back length is around 30 cm, and her chest is on the smaller side. When we choose dresses for her, we sometimes select one size smaller if we are happy for the dress to sit a little shorter along her back. The closer chest fit helps stop the dress from hanging loose.

That is a Dolly-specific fit choice, not a substitute for measuring your own cat. Compare chest girth and back length with the exact product chart, and only choose a closer size when your cat can still walk, sit, stretch and groom comfortably.

Sphynx versus Devon Rex: different coats, same measuring rule

Sphynx and Devon Rex cats can look like cousins from a very fashionable family reunion, but their coats are different. Sphynx are mostly hairless with fine down; Devon Rex cats have short, soft, wavy coats. That difference can matter for warmth and fabric feel, but it does not change the rule for choosing clothing: measure the individual cat.

The International Cat Association describes Sphynx as medium-sized cats, generally around 6–12 lb, while Devon Rex are also medium-sized, with typical adult females around 5–7 lb and males around 7–9 lb. Those ranges overlap, and both breeds vary by sex, muscle, age and individual build. A Sphynx can have a broader, more substantial chest; a Devon Rex can have a finer frame. Neither detail replaces chest girth and back length on your tape measure.

For clothes, the practical difference is comfort and warmth rather than a secret breed-only sizing formula. A Sphynx may appreciate a soft layer sooner because there is very little insulating coat. A Devon Rex may also enjoy light warmth, but their soft wavy coat can change how a fabric feels against the body. In both cases, choose soft fabric, follow the product size chart, supervise new clothing, and stop if your cat looks uncomfortable.

Black, tuxedo and tortoiseshell cats: beautiful labels, terrible size charts

A black cat is a colour description. Tuxedo usually describes a black-and-white bi-colour pattern. Tortoiseshell describes a patterned coat with patches of dark and red or cream. These are not breeds, so they cannot tell you whether a garment will fit.

A black domestic shorthair, a tuxedo rescue cat and a tortoiseshell house cat can all be completely different sizes and shapes. Their chest, neck and back are the useful facts. Their colouring is useful for choosing a very good outfit photo. I support both kinds of research, in that order.

A quick breed-and-size reality check

• Sphynx: often medium, muscular and surprisingly substantial. Measure the chest carefully rather than assuming hairless means small.
• Devon Rex: often small to medium with a fine frame, but still measure the chest and back because individual proportions vary.
• Cornish Rex and other fine-coated cats: light-looking does not mean one universal size. Follow the chart for the garment and the measurements in front of you.
• Domestic and mixed-breed cats: there is no standard body shape. Coat colour or a friendly face does not provide a chest-girth measurement, sadly.

Choosing between sizes

When your measurements sit between sizes, use the specific garment and the fit you want. For a relaxed everyday layer, the larger size is often more comfortable. For a snug warmth layer, follow the product chart closely, provided your cat still has normal freedom to walk, sit, stretch and groom.

Do not rely on weight alone. Weight can be helpful when a product chart includes it, but two cats at the same weight can have different chest girths and back lengths. The tape measure has no favourites.

Your practical next step

Once you have your measurements, start with our cat clothing sizing guide, then compare them with the chart on the product you like. If your cat prefers a full-body style, browse cat pyjamas and onesies. For an easier legs-free layer, look at cat sweaters or cat jackets.

And remember: the right outfit is the one your cat can wear comfortably while continuing their essential work of sleeping, supervising and ignoring you.

> Dolly’s final rule: Measure the cat you have, not the cat you imagine after three flattering photos.
