Trees look smaller outside
Out in an open field, with sky overhead, almost every tree looks smaller than it really is. The most common mistake at a tree farm is bringing home a tree that’s too tall for the room. Measure before you go, and bring a tape measure.
Height
Measure from the floor to the ceiling where the tree will stand. Subtract the height your stand adds, often a few inches, and the height of your topper. Leave a little extra room between the top and the ceiling so it doesn’t look cramped. Many farms have measuring poles in the field to check against.
Width
Trees are often about two-thirds as wide at the bottom as they are tall, so a 7-foot tree might be close to 5 feet across. Measure the floor space you have, and remember that branches spread out a bit more once any netting comes off.
Trunk and stand
Check the largest trunk diameter your stand can hold, and how much water it holds. A common rule is that a tree needs about a quart of water per inch of trunk diameter each day, especially in the first week. If your stand is small, choose a tree with a thinner trunk, or ask the farm to trim the base to fit.
Doorways and your car
Make sure the tree can get through your front door and around any tight corners. A netted tree makes this much easier. Check that your car can carry it too: see tying a tree to your car.
