How Many Lights, Ornaments and Ribbon for Your Tree?
Under-lit trees look sad; under-filled trees look unfinished. These are the rules of thumb decorators use, turned into one chart you can take to the store.
The short answer
The classic rule is about 100 lights per foot of tree (go 150–200 for a dense, glowing look). For ornaments, plan roughly 10–20 per foot. For ribbon, about 3 yards per foot of tree if you weave it through the branches.
For a typical 7.5 ft tree: about 750–1,100 lights, 75–150 ornaments and 20–25 yards of ribbon.
The chart (rules of thumb)
| Tree height | Lights (standard → bright) | Ornaments | Ribbon (woven) |
|---|---|---|---|
| 4 ft | 400 → 600 | 40–80 | ~12 yards |
| 6 ft | 600 → 900 | 60–120 | ~18 yards |
| 7 ft | 700 → 1,000 | 70–140 | ~21 yards |
| 7.5 ft | 750 → 1,100 | 75–150 | ~22 yards |
| 9 ft | 900 → 1,400 | 90–180 | ~27 yards |
These are starting points. Full-shaped trees need the top of each range; slim and pencil trees the bottom. Pre-lit trees usually come with about 100 lights per foot already — add a strand or two if you want more glow.
Hang lights from the inside out
Spiraling lights around the outside gives a "wrapped" look with dark gaps. Decorators work branch by branch instead:
- Plug in and test every strand first.
- Start at the bottom, near the trunk. Run the strand out along a main branch to the tip, then back toward the trunk, and on to the next branch.
- Work up in sections, keeping the outlet end at the bottom.
- Mix depths: some lights deep inside (the glow), most along the outer half (the sparkle).
- Squint test. Step back and squint — dark patches show up instantly.
Ornaments that look full
- Start with basics: plain shatterproof balls in 2–3 sizes and 2–3 colors, tucked deep into the tree to fill gaps.
- Then feature ornaments near the outside at eye level.
- Bigger at the bottom, smaller at the top — it makes the tree look taller.
- Work in triangles: place each style in loose triangles around the tree so colors spread evenly.
Ribbon and garland
- Wired ribbon (2.5–4 inches wide) holds its shape. Tuck it in and out of the branches in loose waves, top to bottom, or as vertical "waterfalls."
- Bead or tinsel garland drapes in swags; plan roughly twice the tree height per loop around, and a few loops per tree.
- Picks and sprays (berries, pine, glitter stems) fill the last gaps — about 1–2 per foot of tree.

How many ornaments for a 7 foot tree?
Roughly 70 to 140, depending on how full the tree is and how large the ornaments are. Fill gaps with plain balls deep inside the branches.
How much ribbon do I need for a Christmas tree?
About 3 yards per foot of tree if you weave it through the branches — roughly 22 yards for a 7.5 foot tree.
How do you put lights on a Christmas tree?
Start at the bottom near the trunk and wrap each main branch from trunk to tip and back, working up in sections, rather than spiraling around the outside.
