I have 2 trees that I need help estimating on how many mini lights I will need. I buy them in 25' strands.

Both trees are oak trees, and I will just be going up to where they begin to branch.

1) 10' tall & 1' in diameter.
2) 10' tall & 1.5' in diameter.

Can anyone help me estimate how many strands I will need? I will be using village lights if that helps any. Thanks.

Village says to add the hight and width to come up with and estimated number of strands needed. Example: you want to wrap a tree 10' up and the tree is 2' wide, the total would be 12 strands. This is the way Village Lighting tells you to estimate the number of Super Mini strands you will need.

I would say 9-12 strands each.

I don't do Christmas lights, but I know a little useful math.

The circumference of a tree can be calculated from its diameter using the formula:

c = π x d

π = 3.14159265

So a tree 1 ft. in diameter is 3.14 ft around.
A tree 1.5 ft. in diameter is 4.71 ft. around.


How densely are you wrapping the trunk? If you were to space the strands 1 in. apart, 10 ft. tall is approx. 121 wraps.

If each wrap is 3.14 ft. long, then 121 x 3.14 = 378 ft.

378 / 25 = just over 15 strands.


If on the other hand you space the strands 1.5 in. apart, 10 ft. tall is 81 wraps.

81 x 3.14 = 255 ft.

255 / 25 = just over 10 strands


If 1.5 in. spacing seems right, then for the other tree that's 4.71 ft. around.

81 x 4.71 = 381.51

382 / 25 = just over 15 strands.

Not to hi-jack your thread but those that are reading this thread, What do you do when you need to cross the road to get the power to the trees? (there are no outlets near the trees). Snow removal = problems.

This sounds like a problem that I would not want to have.

Someone must have run into this. Shopping centers, nursing home entrances, gas stations, how would you do it? :confused:

I would think that the best way to solve that problem would be to have an electrician install a gfci plug at each parking lot island, side of the street, etc. so you wouldnt need to run across pavement. that in itself is a giant tripping liability as well.

bore or cut open driveway and install outlets. Under no circumstances should you leave a trip hazzard. That goes double for commercial properties unless you like being sued.

Dude, that's like 7th grade math.

C'mon now.

Just seemed like a lot of room for inaccuracy in the formula Paul mentioned....

It does give a good estimate number though. Look at the numbers you got from the formula. Pretty close!!

Yeah it does, but if I were in that end of the biz I would want to be as close as I could get... and then probably add for a margin of error too. Interesting how much half an inch spacing difference between strands wrapping around a tree makes too.

awesome math, that is kinda how I do it, except I use a flex tape measure and just wrap it around the tree to get its circumferance.

How many inches apart should I space my mini light strands? 2, 3, 4 inches?

Since I don't do it commercially, I'll just say that the effect was pretty awesome over the past few years at my mom's house at 1.5 inch spacing on a triple trunk mature Japanese maple. We wrapped them all together to where they veered apart at about 5 ft. up, then wrapped 3 main trunks for another 3 ft or so... at that point they came off a separate extension cord with a three way splitter that was fed up through the middle.

My head hurts now. How many wraps of gauze will I need after falling of a snow covered roof while installing Xmas lights?

Funny you say that, I just broke my big toe dropping a wall cap on it!

Sorry for the highjack!

im installing these lights in 9 hours...:)

anyone else got input on spacing?

David Gretzmier

I try to match the spacing on lines to the spacing on the cord. If the mini's are 4 " apart, I go 4", If 3" I go 3. that way it looks even. too close together creates this funky pattern.

We use a concrete cutter all the time to groove concrete driveways and lay the wire in the groove beow grade. I don't know if it would work in your situation...

Thanks for ya'lls help. My first install went pretty well. Here are a few things I learned.

1) Test GFI's prior to install. (we arrived and there was no power at any outlets per xmas lights. 2 out of 4 locations were bad, reset all gfi's and flipped breakers, nothing) HOA is having electrician come in on Monday.

2) Roof's are ALOT steeper once you are up there then they look like from the ground. We clean alot of gutters, and this is steeper than anyone I've ever gone on before. We did along the triangular portoin on the left side where u see that oak leaf, along the facia portion across the drive through, and on top of the ridge of the roof. I was glad to get down!! Picture below:

3) Since there was no power to some of the trees we were wrapping with mini's, we didn't know what was/was not working until we temp powered them up. Half the strands had loose bulbs, which took 1.5 hours to fix. Next time, wrap minis around trees with the power on.

4) Install C9 strands without bulbs, it goes alot faster (did not do this, broken 15 bulbs for the 300+ we put up today)

5) When staking C9's... lay out strand, clip stakes on all (or majority) of sockets, and then install without bulbs. Then go back and bulb up sockets after setting into the ground. This I figured out first time around, worked great.

6) Zook wire from HD (used for hanging mirrors) works great for hanging garland and what not off of masonry walls with nails in them, also good for wrapping around light poles to hang bows and what not on)

7) HD has better prices on extension cords by over 50%, and near 50% cheaper on timers as well. Same exact model. I wasted almost $100 buying these from the supply house. Lights were great no doubt! But accessories I could get alot cheaper at HD.

8) anyone got any tips for a speedy take down?
