Christmas Tree Size Finder

Find the tallest and widest Christmas tree that fits your ceiling and room, with the stand and topper.

How this works

Tree height = ceiling height minus the stand, the topper and 15 cm of clearance. Slim trees are about 45% as wide as they are tall, standard trees 60% and full trees 70%. Keep the tree to about a third of the room width so you can still walk round it.
