Getting the right fit matters more with a collar or lead that you'll use every day for years.
Below is our full size chart for rope and leather styles, along with a straightforward guide to measuring your dog's neck and choosing a lead length that suits how you actually walk.
How to measure your dog's neck
Locate the right spot
Measure where the collar will naturally sit, just below the base of the ears.
Measure snugly
Wrap a flexible tape measure around the neck, leaving enough room to fit two fingers comfortably between the tape and your dog's neck.
Note it down
Record the measurement in inches, then match it to the nearest size in the chart below.
Rope Collars
Made to measure and non-adjustable. Choose the closest inch to your dog's measured neck circumference. Please note our rope collars are measured by the internal circumference and not end to end.

|---|---|---|---|
| 10 | 10" | 25cm | Toy and small breeds |
| 11 | 11" | 28cm | Toy and small breeds |
| 12 | 12" | 30cm | Small breeds |
| 13 | 13" | 33cm | Small to medium breeds |
| 14 | 14" | 36cm | Medium breeds |
| 15 | 15" | 38cm | Medium breeds |
| 16 | 16" | 41cm | Medium to large breeds |
| 17 | 17" | 43cm | Large breeds |
| 18 | 18" | 46cm | Large breeds |
| 19 | 19" | 48cm | Large breeds |
| 20 | 20" | 51cm | Large and giant breeds |
Leather Collars
Adjustable across a range of buckle holes, so each size covers a span rather than one fixed measurement.
| Size | Inches | Approx. cm |
|---|---|---|
| XSmall | 8–12" | 20–30cm |
| Small | 10–14" | 25–36cm |
| Medium | 12–16" | 30–41cm |
| Large | 14–18" | 36–46cm |
| XLarge | 16–20" | 41–51cm |
Leather Leads
Single length of 95–100cm (approximate), with a 19mm diameter for a sturdy, comfortable hold in the hand.
Clip Rope Leads
| Length | Best for |
|---|---|
| 120cm | Everyday walks, giving close control |
| 150cm | More room for your dog to roam while staying easy to manage |
Slip Leads
Available in 100cm and 140cm (approximate), with a 10mm diameter for a comfortable grip.
Re-Measure Regularly
Dogs, like humans, can change size over time, so ensure your measurements are up to date.

Frequently asked questions
What if my dog is between two sizes?
For rope collars, choose the closest available inch, or get in touch about a bespoke size made to your exact measurement. For leather collars, the buckle holes give you a small adjustment range either way, so check where your measurement falls within each size band above.
Should I leave extra room for a growing puppy or thick fur?
Yes, a small allowance is worth adding for puppies still growing into their adult size, or for breeds with a thick neck ruff where the coat adds to the measurement.
Can I get a custom lead length?
Yes, custom lengths are available as part of our bespoke service.
Do rope and leather collars fit differently?
Yes. Rope collars are made to one exact circumference, while leather collars adjust across a range of buckle holes, so it's worth checking which chart applies to the style you're choosing.
