To determine the size of the Christmas tree collar you need, you should measure the diameter of your tree base. Most tree collars range from 20” to 34” round and 9” to 11” tall
. For trees under 7 feet, small collars that measure up to 29 inches in diameter are recommended, while trees that are 7 to 11 feet tall require large collars that come in 34 inches and can cover tree bases up to 32 inches in diameter
. It's important to ensure that the collar is big enough to contain the tree stand completely, while allowing the stand to rest securely inside it, and tall enough to conceal it
