Christmas tree water and stand calculator
A real Christmas tree needs a stand that fits its trunk and holds enough water. Enter the trunk diameter and the stand's usable capacity to compare it with the National Christmas Tree Association's one-quart-per-inch capacity guideline. Add your room height, tree height, topper, and preferred clearance to check whether the tree fits. Check the reservoir daily and keep the cut end submerged; this is a planning check, not a substitute for the stand maker's size rating.

How it works
- 01
The National Christmas Tree Association's stand guideline is 1 quart of water capacity per inch of trunk diameter. The result converts that to gallons and compares it with your stand's usable capacity.
- 02
The trunk-fit check compares the tree's measured diameter with the maximum printed for your stand. The stand must support the trunk without trimming away its outer wood.
- 03
Ceiling space is room height minus tree height and topper height. The height check compares that space with the clearance you want.
Try a real scenario

Inputs3-inch trunk, 6-inch topper, 6-inch clearance, 1-gallon stand rated for a 4-inch trunk
ResultMinimum stand capacity: 0.75 gal. The stand meets the water guideline and trunk rating; 18 inches remain above the topper.
