Many families ask "what size urn do I need" as one of the first questions. Choosing the right urn size begins with how the ashes will be kept. If ashes will be kept together in one vessel, a Large urn is usually the right choice for most Australian adults. If ashes will be shared between loved ones, a Small urn or urn set may be more suitable.

For most Australian adults, a Large urn (3.0–3.2 litres) is usually suitable.

Yurn vessels are designed to live beautifully within the home. If you are selecting an urn for burial or columbarium placement, always confirm any size or material requirements with your cemetery, memorial park, or provider before purchasing.

This guide is designed to help families choose a cremation urn size with greater clarity, confidence, and ease.

Quick Answer

Large is the most common size for a full set of adult ashes.

Small is best for portion ashes, urn sets, children, babies, pets, and some smaller individuals. Extra Large is best for larger individuals, combining ashes, or when you wish to include small keepsakes or objects.

* Individual vessel sizes vary. Always check the product listing for the approximate capacity of each urn.

** Ash volume can vary between individuals depending on height, bone density, and cremation process.

How to Choose the Right Urn Size

• Choose Large if ashes will be kept together for most adults.
• Choose Small if ashes will be shared, divided, or kept in an urn set.
• Choose Extra Large if more capacity is needed for a larger individual or combined ashes.
• If you want to include notes or small mementos, extra internal space may be helpful.
• If you plan to scatter some ashes and keep some, you may need both an urn and a scattering vessel.

For most Australian adults, a Large urn holding around 3.0 to 3.2 litres is usually suitable.

Can a small urn hold all ashes?

A Small urn can hold all ashes for a baby, child, pet, or some smaller individuals. It can also hold a portion of ashes when ashes are divided between loved ones.

If you are unsure, it can help to ask the crematorium for the approximate ash volume returned. In many cases, choosing the next size up provides added peace of mind.

Is it legal to keep cremated ashes in the home?

Yes. In Australia, it is safe and common for families to hold onto loved ones by using a modern cremation urn in the home. If you are scattering ashes, it can help to check with your local authorities who may require permits or permission.
