The Definitive Guide to Choosing the Right Size Cremation Urn for Your Loved One

Losing a loved one is an extraordinarily difficult experience, and choosing the right-sized cremation urn is a crucial step in the healing process. At The Urn Centre, we understand the importance of this decision and are here to provide guidance and support. In this comprehensive guide, we will explore the details, helping you navigate urn capacity based on ashes, dimensions, personalisation options, and offering heartfelt ways to honour your loved one's memory.

Determine Ash Quantity and Urn Capacity: Understanding the quantity of ashes produced is key to selecting the appropriate urn size. On average, the cremation of human remains results in approximately 2-4 litres of ashes. At The Urn Centre, our urns are categorised based on their capacity, making it easier for you to find the right fit.

Urn Size for Human Ashes

Deceased Pre Death Weight (KG) URN SIZE / VOLUME REQUIRED (Litres) WEIGHT OF ASHES(Approx) (grams/kg)
0.45kg 17ml 13 g
28.5KG 1 Litre 850 g
76.2KG 2.8 Litres 2.17 kg


Note: Height is also a contributing factor towards the total size you will need. Taller people will inherently have longer bones so there will be more ash. Fat is burnt away during the cremation process, so will have less of a bearing on the final amount of ashes. This should be taken into account when calculating the urn you will need.

Consider the Dimensions and Display Space: Carefully consider where you plan to display or inter the cremation urn. Take measurements of the available space to ensure a perfect fit. A compact urn might be ideal for a cherished spot at home, while a larger urn can make a statement as the focal point of a memorial service or columbarium. Our wide range of dimensions ensures you find the ideal size for your specific requirements.

Reflect on Design, Style, and Material: At The Urn Centre, we offer an extensive selection of designs, styles, and materials to suit different tastes and preferences. Reflect on your loved one's personality and interests when choosing an urn that truly embodies their essence. From classic and timeless designs to contemporary and unique options, our collection provides ample choices to create a fitting tribute.

Seek Input and Share the Decision: Involve family members and close friends in the decision-making process. Their input and support can provide solace and ensure a collective decision that reflects the wishes and values of your loved one. Sharing this experience fosters a sense of togetherness during this challenging time.

Embrace Personalisation: Personalising the cremation urn adds a deeply personal and meaningful touch to the memorial. The Urn Centre offers a range of customisation options to honour your loved one's unique story. Consider engraving their name, a significant date, or a heartfelt message on the urn. Incorporating photos, symbols, or artwork can further capture and celebrate their life.

Paying Tribute Beyond the Urn: Remember that commemorating your loved one's life goes beyond the urn itself. Consider other ways to honour their memory, such as creating a memorial space with photographs, mementos, or a memory box. The Urn Centre also offers companion keepsakes, jewellery, and scattering options, providing additional ways to hold your loved one close.
