If you’re here because you’re trying to make one practical decision after losing your Whippet, I’m so sorry. This guide keeps urn sizing clear and steady—so you can choose a capacity that fits comfortably without second-guessing it.
Quick answer
- Sizing rule: plan for about 1 cubic inch per pound of body weight.
- Typical adult Whippet weight: about 25–40 lb.
- Minimum urn capacity: about 25–40 cubic inches.
- Comfort range (roomier fit): about 30–48 cubic inches (adds ~20%).
- Most Whippets fit best in a Medium urn (25–60 cu in). If your Whippet was a larger mix (or weight is an estimate), sizing up to Large can be the calmer choice.

The sizing rule (1 cubic inch per lb) and why we still size up
Urn capacity is measured in cubic inches. A practical starting point is one cubic inch of urn capacity for each pound of your dog’s weight. Many families choose a little more than the minimum because it helps the inner bag settle more easily, makes closure feel calmer, and gives breathing room if weight is an estimate (or if you want to include a small memento).

Whippet weight to urn capacity (cubic inches)
If you have a recent vet record, use that number. If not, use your best estimate and lean toward the comfort number for an easier fit.
| Your dog’s weight | Minimum capacity (1:1) | Comfort capacity (add ~20%) | Usually a good fit in |
|---|---|---|---|
| 25 lb (smaller adult) | 25 cu in | 30 cu in | Medium |
| 30 lb | 30 cu in | 36 cu in | Medium |
| 35 lb | 35 cu in | 42 cu in | Medium |
| 40 lb (upper end) | 40 cu in | 48 cu in | Medium |
| 45–60 lb (mix / larger-than-typical) | 45–60 cu in | 54–72 cu in | Large (calmer fit) |
Which Funeral.com size category fits most Whippets?
Most Whippets fit best in a Medium pet urn (25–60 cubic inches). Medium gives plenty of breathing room for the typical Whippet range, and choosing a listed capacity that meets your comfort number usually makes placement and closure easier.
- Shop Medium Pet Urns (25–60 cu in)
- Shop Large Pet Urns (60–100 cu in) (if your Whippet was a larger mix or you want extra room)
- Browse all Dog Urns
Tip: Shop by the urn’s listed capacity. Some styles (especially photo urns or memory-box designs with compartments) can have less usable interior space than they appear to from the outside.
Size up if… (a simple rule that prevents a tight fit)
Size up if your dog’s weight is an estimate, your dog is a mix, your dog is big-framed or very muscular, you want room for mementos (tag, note, fur clipping), or you want the easiest closure with the inner bag. If your dog’s weight is close to the top of this size tier, choosing the next tier up is usually the calmer choice because it avoids a tight fit.
Sharing plan options (keepsakes and jewelry)
If more than one person wants a portion of ashes, a gentle plan is one primary urn plus keepsakes (or jewelry) so you don’t have to reopen the main urn repeatedly.
