If you’re here because you’re trying to make one practical decision after losing your Newfoundland, 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 Newfoundland weight: about 100–150 lb (many females closer to ~100–120; many males closer to ~130–150).
- Minimum urn capacity: about 100–150 cubic inches.
- Comfort range (roomier fit): about 120–180 cubic inches (adds ~20%).
- Most Newfoundlands need an Extra Large urn (over 100 cu in). Choosing a higher-capacity XL is often the calmer choice for an easier closure with the inner bag.

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 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.

Newfoundland 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 giant breeds, extra capacity can make the inner bag easier to settle and closure easier.
| Your dog’s weight | Minimum capacity (1:1) | Comfort capacity (add ~20%) | Most likely size tier |
|---|---|---|---|
| 100 lb (common female / smaller adult) | 100 cu in | 120 cu in | Extra Large (over 100) |
| 120 lb | 120 cu in | 144 cu in | Extra Large (over 100) |
| 130 lb (common male) | 130 cu in | 156 cu in | Extra Large (over 100) (higher capacity recommended) |
| 150 lb (upper end / big-framed) | 150 cu in | 180 cu in | Extra Large (over 100) (higher capacity recommended) |
| 170+ lb (very large / mix) | 170+ cu in | 204+ cu in | Extra Large (over 100) (choose the highest listed capacity you can) |
Which Funeral.com size category fits most Newfoundlands?
Most Newfoundlands need an Extra Large pet urn (capacities over 100 cubic inches). The important detail is that “XL” covers a range of capacities—so shop by the urn’s listed capacity, not just the label. If your comfort estimate is 150+ cubic inches (common for many males), prioritize higher-capacity XL designs so closure doesn’t feel tight.
- Shop Extra Large Pet Urns (over 100 cu in)
- Shop Large Pet Urns (60–100 cu in) (only if your dog was under 100 lb and your comfort estimate stays below 100)
- Browse all Dog Urns
Tip: Some urn styles (including photo urns or memory-box designs) may have internal compartments that reduce usable capacity. If you’re choosing between two XL capacities, the higher capacity is usually the calmer choice.
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.
For Newfoundlands, the main decision point is right around 100 cubic inches. If your dog was close to 100 lb (or weight is an estimate), choosing Extra Large usually removes the stress.
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. For giant breeds, this can also make the main urn easier to manage long-term.
