Yes, there is a weight limit for cremation. Most funeral homes have a weight limit of 300 pounds for cremation. This is because the average cremation chamber is only able to accommodate one standard size casket, which typically has a weight limit of 300 pounds. However, some funeral homes do have larger cremation chambers that are able to accommodate two or more caskets at once. If you are arrangements are being made for someone who exceeds the weight limit, you should ask the funeral home if they have a larger chamber or if they will be able to make arrangements with another funeral home that does.
