Step 1

How to Measure Your Dog's Neck

Always measure your dog directly — not an existing collar. Different materials (BioThane®, Paracord, PPM rope, Bridle Leather) sit differently on the neck. A few minutes here saves a return trip.

01
⭐ Recommended

The Two-Finger Rule

The tried-and-true method used by makers and groomers alike.
  • Wrap a soft tape measure around the neck where the collar naturally sits.
  • The tape should lie flat — then slide two fingers underneath.
  • The measurement with fingers in place is your "Cinderella Fit" — use this when ordering.
02

Snug Measurement + 1.5"

Great if you don't have a helper handy.
  • Measure snugly around the neck with no fingers underneath — tape flat to skin.
  • Add 1.5 inches for natural movement, breathing, and comfort.
  • Use this final adjusted figure when selecting your size.

Measure the dog, not the collar

Wrap your tape where the collar naturally rests. Ensure you can slide two fingers between tape and neck before noting the figure.

What to avoid

Don't measure an old collar

Materials stretch and compress differently over time. Always go back to the dog for a fresh measurement.

Greenwich Yarn Collars — Head Measurement Required
These slip-on and clip styles are non-adjustable and cannot be resized after making. Measure the widest part of your dog's head (around the ears) — not the neck. A wrong measurement here means the collar won't go on at all.
Step 2

The Sizing Pyramid — True to Every Inch

I use a 3D-printed sizing pyramid, calibrated to every collar inch size, to verify every collar I make before it leaves the studio. It isn't guesswork — it's precision.

What the pyramid does

Every collar is verified on my 3D-printed sizing pyramid before leaving the studio. Calibrated to each inch size — when I slide your collar onto it, I confirm every adjustment hole is exactly where it should be.

How the size ranges work

The tightest hole fits the smallest neck in that range.

Example — Size 11–13.5"
Tightest hole = snug on an 11" neck. Each extra hole adds room up to 13.5" — space for coat changes or a more relaxed fit.

Choosing the right size range

Use your neck measurement to find the correct range. If your dog measures 11.5" with the Two-Finger Rule, the 11–13.5" size gives a snug start with comfortable room beyond. You're not estimating — it's been verified.

Made to your specification

The pyramid ensures "to your spec" is never just a promise — it's something I can physically demonstrate in the studio before your collar ever leaves Oxford.

Matching a Current Favourite

Want to replicate the exact fit of a collar or lead you already love? Here's how.

Clip end → Material start

Clip Collars

Measure from the end of the clip fitting to the start of the collar material.

dog's hole Buckle base → Used hole

Buckle Collars

Measure from the base of the buckle to the hole your dog currently uses.

Handle end → Clip tip

Dog Leads

Lay flat. Measure from the tip of the clip to the end of the handle for total lead length.

Slider → Handle +30cm auto-added

Slip & Figure-8 Leads

Measure slider to handle end. I automatically add 30cm for the slip loop — don't add it yourself.
