If you’re here because you’re trying to make one practical decision after losing your Brittany, I’m so sorry. This guide keeps urn sizing calm and straightforward—so you can pick 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 Brittany weight: about 30–40 lb.
- Minimum urn capacity: about 30–40 cubic inches.
- Comfort range (roomier fit): about 36–48 cubic inches (adds ~20%).
- Most Brittanys fit best in a Medium urn (especially if you want an easier closure with the inner bag).
Start shopping here: Pet Urns for Dogs. Most Brittany families compare: Medium Pet Urns and (if you want extra breathing room) Large Pet Urns.
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 every pound of your dog’s weight. Many families choose a little more than the minimum because it helps the inner bag settle more easily and makes the closure feel calmer—especially if your dog’s weight is an estimate or you want room for a small memento.

Brittany 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 range—especially if your Brittany was big-framed, very muscular, or a mix.
| Your Brittany’s weight | Minimum capacity (1:1) | Comfort capacity (add ~20%) | Usually a good fit in |
|---|---|---|---|
| 30 lb | 30 cu in | 36 cu in | Medium |
| 35 lb | 35 cu in | 42 cu in | Medium |
| 40 lb (top end) | 40 cu in | 48 cu in | Medium (choose a higher listed capacity) |
| 45–50 lb (larger / mix / overweight) | 45–50 cu in | 54–60 cu in | Medium (roomier end of the range) or Large (extra breathing room) |
Which Funeral.com size category fits most Brittanys?
Most Brittanys fit comfortably in a Medium pet urn. Medium urns typically cover a wide capacity range, which is helpful for active, athletic dogs where you want a calm, easy closure instead of a tight fit. If you’re adding mementos or your dog’s weight is an estimate, choosing a higher-capacity Medium is usually the simplest move.
- Shop Medium Pet Urns
- Shop Large Pet Urns (if you want extra breathing room)
- Shop Small Pet Urns (usually for much smaller pets or a portion of ashes)
- Shop Extra Large Pet Urns (typically for very large dogs)
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.
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 you’re choosing between two capacities, the larger option is usually the calmer choice because it avoids a tight fit.

FAQ
What size urn do I need for a Brittany?
Most Brittany dogs are around 30–40 lb, so a typical minimum range is 30–40 cubic inches. For a calmer fit, many families choose a little extra capacity (about 36–48 cubic inches).
What size urn do I need for a 30 lb Brittany?
Start with 30 cubic inches minimum. For comfort, aim for about 36 cubic inches (+20%). A Medium urn is typically a great fit.
What size urn do I need for a 35 lb Brittany?
Start with 35 cubic inches minimum. For a roomier fit, aim for about 42 cubic inches. Most families shop Medium.
What size urn do I need for a 40 lb Brittany?
Start with 40 cubic inches minimum. For comfort, aim for about 48 cubic inches. A Medium urn works well—just choose a higher listed capacity so it doesn’t feel tight.
Should I choose a Small or Medium urn for a Brittany?
Most Brittanys fit best in Medium. Small is typically used for much smaller pets (or a portion of ashes), while Medium gives you the capacity range that matches most Brittany weights and allows an easier closure.
My Brittany is a mix (or overweight). What size should I get?
Use your dog’s actual weight if you know it, and add buffer for comfort. Many Brittany mixes still fit well in Medium, especially in the roomier end of the capacity range.
How much extra space (buffer) should I add?
A common approach is about 15–20% over the minimum estimate. This helps the inner bag settle comfortably and reduces the chance of a tight fit.
Can I put a collar tag or small memento inside the urn?
Often, yes—just plan for it. If you want room for a tag, note, or small token, choosing a higher-capacity option (or sizing up) makes everything feel easier.
What if I’m splitting ashes between family members?
A simple plan is one primary urn plus keepsakes or jewelry so you don’t have to reopen the main urn repeatedly. Keepsakes can also be meaningful even if you’re not splitting evenly.
How can I double-check the right capacity before ordering?
Use the Pet Urn Size Calculator, then choose an urn whose listed capacity meets or exceeds your comfort target. You can also compare with the Urn Size Chart & Complete Guide.
