Sizing guide

What size urn
do I need?

Allow about one cubic inch of capacity for every pound the person weighed. Someone who weighed 160 pounds needs roughly 160 cubic inches. That is the standard the funeral industry uses, and it is nearly always enough.

Shared between how many urns?

Many families divide ashes so more than one person can keep them close.

The size to choose

The 200 lb size

They need about 160 cubic inches of capacity, and this size holds 220. Sizes are named for the person's weight in life, never the urn's own weight.

The standard sizes

Sized by the person, not the vessel

Urn sizes are named for the weight of the person in life, never the weight of the urn itself. Each of these is built at 1.1 cubic inches per pound, so every size already carries about ten percent of extra room.

Small sculptural keepsakes hold 6 to 10 cubic inches, a portion of the ashes rather than all of them.

Two honest rules

When you are between sizes, go up

Ashes settle and pour more easily into a vessel with a little room to spare, and extra capacity causes no problem at all. The only mistake worth avoiding is choosing something clearly too small. You do not need an exact weight; an estimate is genuinely fine.

And if the ashes will be shared, size each urn for its own share, not for the whole. A 160 pound person divided between two urns needs about 80 cubic inches in each, which is a much smaller vessel than most people guess. The calculator above does that arithmetic for you.

Our largest size suits someone of about 200 pounds and holds 220 cubic inches, so it still fits someone a little over that. Beyond it, dividing between two urns is the usual answer, and a completely normal one.

If it helps

We make urns in every one of these sizes

Everform is a small studio in Massachusetts. Each urn is made in soft stone-white engineered ceramic, finished by hand, and offered in all five sizes above, so whichever size the calculator gave you is a size we make.

Common questions

What size urn do I need?
Allow about one cubic inch of urn capacity for every pound the person weighed before cremation. Someone who weighed 160 pounds needs roughly 160 cubic inches. Our sizes are built at 1.1 cubic inches per pound, so each one already includes about 10 percent of extra room.
Does the size number mean the weight of the urn?
No. A size labelled 150 lbs suits someone who weighed about 150 pounds in life. The urn itself weighs only a few pounds.
What is the standard adult urn size?
Most adults are served by a capacity of about 200 cubic inches. In our range that is the 200 lb size, which holds 220 cubic inches.
What if I am between two sizes?
Choose the larger one. Ashes settle and pour more easily into a size with a little room to spare, and extra capacity causes no problem. Too little does.
What if the person weighed more than 200 pounds?
Our largest size holds 220 cubic inches, so it still suits someone a little over 200 pounds. Beyond about 220 pounds, families often divide the ashes between two urns so more than one person can keep them close, or keep a portion and scatter the rest. Email hello@myeverform.com and we will help you work it out.
How much smaller are the sculptural urns?
The sculptural designs, such as the animals and the cottages, hold 6 to 10 cubic inches. They are made to hold a portion of ashes rather than all of them, which is why many families order more than one so each person has something to keep.
What if I know their weight in kilograms?
Multiply kilograms by 2.2 to get pounds, which is also roughly the cubic inches of capacity needed. Someone who weighed 75 kilograms is about 165 pounds and needs about 165 cubic inches. The calculator on this page accepts kilograms directly.
What size does each urn need if the ashes are shared?
Size each urn for its own share, not for the whole. Divide the person's weight by the number of urns: a 160 pound person divided between two urns needs about 80 cubic inches in each. Small keepsake urns holding a few cubic inches are also made for keeping just a portion close.
Does the urn need to be exact?
No. An estimate of the person's weight is enough. The one to watch is choosing something clearly too small, so when in doubt go up a size.
