Frequently asked questions

What is Christmas Tree Calculator?

Work out how many string lights, ornaments and how much garland your Christmas tree needs from its height, base width and decoration density, plus a cost estimate.

When would I actually use this?

Buying decorations for a tree before you own it, or checking whether last year's box is enough: how many light strings and ornaments a given height carries, how much garland goes round it, and what the lot costs.

What is the most common mistake?

Buying garland by the tree's height. Garland goes round, not up: the length you need is the girth multiplied by the number of times you wrap it, so a short wide tree eats more than a tall narrow one of the same volume. Height sets the lights and the ornaments; width sets the garland.

How is Christmas Tree Calculator different from Celtic Tree Zodiac Calculator?

They sit next to each other but answer different questions: Celtic Tree Zodiac Calculator is the one to open when you need it to map your birth date to your Celtic tree sign in the 13-tree Ogham calendar, with its Ogham letter, dates and a short trait profile. Pick whichever matches what you're starting from — both are free.

Is there a tool for the next step?

24 Game Solver is the closest one after this: Enter four numbers and find every way to reach 24 using +, −, × and ÷ with each number exactly once.

What else is worth having open alongside it?

Baby Eye Color Predictor and Baby Name Generator — they come up in the same task often enough to be worth a second tab.

Where do the figures come from?

Trade rules of thumb for the density — so many bulbs and ornaments per foot of height, at three levels of how full you want it — and plain geometry for the garland, which is the base circumference times the number of turns the spacing allows. The costs are unit prices you set: nothing here knows what a shop charges.
