If you’re here because you’re trying to make one practical decision after losing your Boxer, I’m sorry. This guide keeps urn sizing simple and calm—so you can choose a size that fits comfortably without second-guessing it.
Quick answer
- Rule of thumb: choose about 1 cubic inch per pound of body weight.
- Typical adult Boxer weight: about 55–80 lb.
- Minimum capacity: about 55–80 cubic inches.
- Comfort range (roomier fit): about 66–96 cubic inches (adds ~20%).
- Most Boxers fit best in a Large urn (60–100 cubic inches). If your Boxer’s weight is an estimate or you’re adding mementos, choose the roomier option.
Start shopping here: Pet Urns for Dogs. Most Boxers will shop comfortably in: Large Pet Urns (60–100 cu in). If you need more than 100 cubic inches: Extra Large Pet Urns (over 100 cu in).
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 1 cubic inch per pound of your dog’s body weight. Many families choose a little more than the minimum because it makes placement easier and helps avoid a tight closure—especially if the weight you have is an estimate.
If you want to double-check your number, use the Pet Urn Size Calculator and compare it with the Urn Size Chart & Complete Guide.
Boxer 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. Most Boxers land solidly in the Large tier once you add a buffer.
| Your Boxer’s weight | Minimum capacity (1:1) | Comfort capacity (add ~20%) | Usually a good fit in |
|---|---|---|---|
| 55 lb | 55 cu in | 66 cu in | Large |
| 60 lb | 60 cu in | 72 cu in | Large |
| 70 lb | 70 cu in | 84 cu in | Large |
| 80 lb | 80 cu in | 96 cu in | Large |
| 90 lb (large frame / overweight) | 90 cu in | 108 cu in | Extra Large (comfort fit) |
Which Funeral.com size category fits most Boxers?
Most Boxers fit best in a Large pet urn because Large typically covers 60–100 cubic inches, which matches the comfort estimate for many adult Boxers. If your dog was heavier than expected, big-framed, or your comfort number is over 100, Extra Large is usually the calmer choice because it avoids a tight fit.
Tip: Shop by listed capacity. Some designs (especially photo urns or memory-box styles 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.
