How tree size is calculated
Leave about 12 inches between the top of the tree and the ceiling for a topper, or about 6 inches without one. Artificial tree heights include their stand. A real tree sits about 4 inches higher in its stand, so the calculator subtracts that too. Width is based on typical profiles: full trees are about 60% as wide as they are tall, slim trees about 40% and pencil trees about 25%.

Frequently asked questions
What size Christmas tree for an 8 foot ceiling?
A 7 ft tree leaves about a foot for a topper. Without a topper, a 7.5 ft tree fits.
What size Christmas tree for a 9 foot ceiling?
A 7.5 ft artificial tree with a topper. For a real tree, buy one sold as 7–8 ft and keep it at 7.5 ft or under, since the stand adds a few inches.
How wide is a 7.5 ft Christmas tree?
A full 7.5 ft tree is about 4.5 ft (54″) wide, a slim one about 3 ft and a pencil tree about 2 ft.
What size tree skirt do I need?
Choose a skirt close to the width of the lowest branches. A 48″ skirt suits most 6.5–7.5 ft trees and 56–60″ suits 9 ft trees.
