An artificial Christmas tree that is too small looks lost. One that is too large overwhelms the room. Choosing the right size transforms your holiday decor. See our full range at CGA products.

Why Size Matters
The right tree size creates visual balance. The CPSC also warns that improperly sized trees near heat sources create fire hazards.
Height Guidelines
Golden rule: Tree height = ceiling height minus 6-12 inches for the topper. A 7ft tree fits an 8ft ceiling. A 9ft tree needs a 10ft ceiling.
| Ceiling | Tree | Topper Clearance |
|---|---|---|
| 8 ft | 7-7.5 ft | 6-12 in |
| 9 ft | 8-8.5 ft | 6-12 in |
| 10 ft | 9-9.5 ft | 6-12 in |
| 12-14 ft | 10-12 ft | 12-18 in |
| 14-20 ft | 12-15 ft | 18-24 in |

Width & Diameter
Standard width: 7ft = 54-60″, 8ft = 60-66″, 9ft = 66-72″. The diameter determines floor space needed.
Room Size Considerations
Tree should occupy no more than 25% of floor area visually. In a 12x12ft room, a 5ft diameter tree (~20 sq ft) occupies ~14% of floor space — ideal.
Ceiling Clearance
Minimum 3ft clearance around pathways. Standard doorway height is 80in — a 7ft tree must be carried through at an angle or on its side.
Quick Size Reference Chart
| Room | Tree Height | Width |
|---|---|---|
| 10×10 ft | 4-5 ft | 36-42″ |
| 12×12 ft | 6-7 ft | 48-54″ |
| 15×15 ft | 7.5-9 ft | 60-72″ |
| Great room | 9-12 ft | 66-84″ |
| Commercial | 12-20 ft | 84-144″ |
Slim & Pencil Trees
Slim trees (30-36″ diameter) are perfect for tight spaces — apartments, hallways, corners. Popular sizes: 6ft slim for standard rooms, 7ft slim for taller rooms.
Commercial Display Tips
For hotels, malls, and offices: measure the tallest ceiling dimension. Leave 2-3ft clearance for large tree toppers. Wide-profile trees (72-84″ diameter) work best in open lobbies.
