What Size Urn Do I Need?

Cremation urns hold the remains of loved ones, close friends, life partners, and pets. Like a cemetery plot, it’s best to think of an urn as a person’s final resting place.

Size Urn

Choosing cremation urns is an often-overlooked aspect of end-of-life planning. However, it’s an important decision that should be made carefully. There are practical considerations when choosing an urn and honoring the deceased’s personality and preferences.

We’ve put together this guide to help you choose the correct size urn for your deceased loved one or pet.

What Type of Urn Should I Get?

The first thing to consider is the type of use and where the urn will be placed. Answering these questions can make the process of choosing an urn simpler.

Type of Urn
  • Will the ashes be scattered?
  • Will the urn be put in a mausoleum or a family cemetery plot?
  • Should the urn be large enough to hold all of the cremated remains?
  • Will all or a portion of the ashes be kept in a memorial urn in your home?
  • Do family members want the ash shared for keepsakes?
  • Will the urn be kept in a columbarium niche?
  • Do you want to save a portion of your loved one’s ashes as cremation jewelry?
  • Will two adults be interred together in the end, necessitating the use of companion urns?
  • Is the urn going to be kept in an urn vault?

Answering these questions will help you understand the type of urn you need.

What size of urn should I get?

When you have determined where the cremation urn will be placed, you can choose an urn based on its capacity. Prior to cremation, urns are usually sized to correspond to the deceased’s weight.

Urns range in size from small to extra-large. Before cremation, determine the deceased person’s or pet’s approximate weight.

What size of urn should I get

According to industry standards, every pound of human weight requires 1 cubic inch of urn space. For example, a person weighing 170 pounds will require an urn with minimum 170 cubic inches space.

To figure out how much cremation your loved one will need, use this formula:

1 cubic inch = 1 pound of weight. 

For example, a cat weighing 10 pounds before cremation requires an urn with at least 10 cubic inches of capacity.

It’s important to keep in mind that urns shouldn’t be too big or too small, but it’s fine to have extra room in your memorial urn, especially if you wish to incorporate some tiny mementos with the remains.

Cremation Urn Styles

Now that you know how cremation urn sizes function, choosing the appropriate vessel for your loved one will be easier. Below are some of the options you have.

Cremation Urn Styles

Standard Size Cremation Urns

A standard size urn is 200 cubic inches. The majority of urns you’ll come across will say “adult,” “standard,” or just “urn” without specifying the size. The average capacity of most human urns is 200 cubic inches. However, there are also smaller or larger urns of within 175 – 300 cubic inches.

Companion Urn

True love is reflected in the creation of companion urns for two people. The link between two lovers might be so strong and lasting that they or their families want to remember and cherish it after they die. A companion urn allow the ashes of two people to be kept side by side for eternity, often in distinct compartments.

Companion Urn

These urns usually hold 400 cubic inches or more and can be manufactured with single or separate compartments. If you use a divider, both sides will be about 200 cubic inches. Check the dimensions on each product page, then use the same computations as before to see if the urn is appropriate.

Keepsake Urn

Keepsake urns come in various sizes, with some holding as little as one cubic inch of remains and others holding within 100 cubic inches. Choose your keepsake urn wisely, depending on its intended use.

It is normally advisable to acquire several 50+ cubic inch keepsake urns if you want to split the remains among several families.

A keepsake urn is substantially smaller than a regular urn and is designed to hold only a modest amount of cremains. These are available in various styles, from a copy of a conventional metal urn to a miniature glass tube.

Splitting cremains into souvenir urns may be ideal if numerous family members wish to keep a loved one close to them. Some folks choose a traditional urn as well as multiple keepsake urns. 

Pet Size Cremation Urn

Pet cremation urns come in a wide range of styles. For pet urns, there is no specified capacity or size. This is due to the fact that there are small dogs and cats, as well as enormous dog breeds. A ten cubic urn will suffice for some of these. For others, such as an English Mastiff, a 300 or even 400 cubic inch urn may be required.

Pet Size Cremation Urn

Pet urns often come in sizes ranging from 10 to 20 cubic inches to 200 cubic inches. Apply the rule of thumb that (1 pound of body weight equals 1 cubic inch of urn) to determine the appropriate urn size for your dog, cat, or other pet.

You may desire a niche size urn if you plan to bury your loved one in a columbarium. Ask the columbarium to provide the dimensions for the niche urn so that you can choose the proper size and shape of the urn.

Cremation Jewelry

This usually entails inserting a little amount of cremains into jewelry. Ashes can be blended with colored glass or encased in a pendant or small cylinder worn as a necklace pendant. In most cases, a standard urn will be required to retain the majority of your loved one’s cremains.

Display Urns

Display urns are available in various sizes and designs, in addition to a variety of sizes. When selecting a display urn, keep in mind the area where the urn will be placed.

Many people, for example, like to keep urns with their loved one’s ashes in the sitting room or in other locations where the family gathers frequently. When the family comes gathered in that area, so it serves as a loving memory of that individual.

Take the measurements of the place where the urn will be kept before you buy it, whether on a mantle, a bookshelf, or anywhere else, to ensure you get the right size.
