# How many lights do you need on a 6ft christmas tree

## How Many Lights Do I Need for My Christmas Tree?

Posted December 4, 2021

Whether you’ve got a real or an artificial Christmas tree, every tree needs Christmas lights to make it look truly festive. However, getting the right amount of lights can be tricky. Follow our guide to make sure you achieve the look you want.

**How Many Lights Do I Need?**

For a basic look our number one rule is at least 100 bulbs per 1ft of tree – so that would mean a 6ft tree needs a minimum of 600 LEDs. For a fuller look, you can add as many lights as you want but we recommend upwards of 700 for a 6ft tree.

**What About Different Styles?**

The different styles of lights will impact the number of bulbs you need for your tree as each light style has a different placement and you can achieve different looks with them.

String lights are a classic light otherwise known as fairy lights and are what most people think of first when it comes to decorating the tree. String lights are the most spread out light style which look fantastic for a twinkling understated look but if you want to achieve a fuller look, you may need to add more lights. Our recommendations below will help you make the right choice whatever your preference on style.

**Recommended numbers:**

6ft Trees = **600 LEDs**

7ft Trees = **800 LEDS**

8ft Trees = **1000 LEDS**

9-10ft Trees = **1200 LEDS**

**2. Compact Cluster Lights**

Otherwise known as Christmas Tree Lights these compact cluster lights are designed to give your tree a really full and bright look as they offer many more lights per metre when compared to classic string lights. There is 2.5cm spacing between bulbs and they are specifically designed for Christmas trees, making them the ideal choice. We recommend the following numbers to achieve the desired full look.

**Recommended numbers:**

6ft Trees = **750 LEDs**

7ft Trees = **1000 LEDS**

8ft Trees = **1500 LEDS**

9-10ft Trees = **2000 LEDS**

**3. Cluster Lights**

Cluster Lights have 4 x as many lights per metre than string lights, and only 1.5cm spacing between bulbs versus string lights 5cm spacing and therefore are already designed to offer a full look. We recommend the following numbers to achieve a well-lit glow for your Christmas tree.

**Recommended numbers:**

6ft Trees = **480 LEDs**

7ft Trees = **720 LEDS**

8ft Trees = **960 LEDS**

9-10ft Trees = **1500 LEDS**

**4. Pin Wire Lights**

Pin wire lights are becoming increasingly popular and it's no surprise why! These stunning LED Christmas lights sit on a very discreet wire which blend in perfectly with your tree and appear almost invisible. The bulbs are a different shape from other Christmas lights and give a more rounded glow.

**Recommended numbers for Pin Wire Compact Clusters:**

6ft Trees = **750 LEDs**

7ft Trees = **1000 LEDS**

8ft Trees = **1500 LEDS**

9-10ft Trees = **2000 LEDS**

**What About Different Colours?**

Whilst colour shouldn't impact the number of lights you need, sometimes brighter lights can have a harsher appearance and you may require less. Therefore, if you want a really bright cool white tree or a multicoloured tree, you probably want to go for a string light so that the lights are more spread out and not overwhelming.

For subtler colours like warm white and copper glow, you are better off going for compact clusters or cluster lights as the fuller appearance will really complement these colours.

## The Omni Calculator computes how many lights to put on Christmas trees.

How many lights should go on a Christmas tree?

This question gets asked so often during the holidays that everyone from retailers like Lowe’s to publications like Real Simple and Better Homes & Gardens have tried to answer it.

“A good rule of thumb is 100 lights for every foot-and-a-half of tree,” according to Lowe’s. But Better Homes & Gardens recommends using three 100-light sets for every foot of a tree’s height. And Real Simple suggests 100 lights for every foot.

Since there’s no consensus about just how many lights is right, trimming a tree can be daunting for novice decorators. It’s even given headaches to mathematicians like Troy Henderson, a professor at the University of Mobile’s College of Arts and Sciences in Alabama. Last year, he developed what he describes as a hack to perfectly light a Christmas tree. By thinking of a holiday evergreen as an inverted cone, Henderson used the mathematical concept known as the conical helix to determine the right number of lights for his tree. He explained:

“Our Christmas tree is 3½ feet wide at its base and 8 feet tall. When using 75 feet of lights, the vertical spacing between rotations is about 7 inches. This ensures that if we begin wrapping the lights in a conical helix pattern beginning at the bottom of the tree and vertically space the lights by about 7 inches between successive rotations, the strands of lights will terminate precisely at the top of the tree.”

Henderson has made his Christmas tree light-spacing formula available to the public, and Dominik Czernia and Álvaro Díez, physics doctoral candidates studying in Poland and Turkey, respectively, have expanded on the mathematician’s work. They feature their approach on a web tool called the Omni Calculator. The free calculator factors in tree lights and ornaments and provides users with step-by-step computation and visualization. To use it, you’ll need to know some basic information, such as your tree’s height and bottom diameter, the length and spacing of the light strands, and the diameter of the ornaments you plan to use.

So who’s most likely to use a Christmas tree calculator? Is it designed for the math-and-science crowd or for anyone who wants a perfectly decorated tree? I interviewed Czernia and Omni Calculator Project founder Mateusz Mucha about the tool.

Who knew that decorating a Christmas tree even stumps physicists? What prompted you all to develop a web tool that could simplify this process for everyone?

**Dominik Czernia**

We had been wondering how many lights and ornaments make a Christmas tree so beautiful. To our surprise, it was impossible for us to make at least some rough estimations. With the help of Dr. Henderson’s formula, we developed our intuitive tool with visualization of your perfect tree with lights and baubles. The best thing about it is the simplicity — all you need to enter are your tree’s dimensions.

**Nadra Nittle**

The conical helix is the key to the calculator. Can you describe how this pattern works in more detail?

**Dominik Czernia**

We surely can all agree that when we look at the Christmas tree, its shape reminds us of a cone, a pyramid with a circular base. So what does the conical helix have in common with a cone? Imagine you’ve got a ribbon that you attach to the top of a cone. Then start wrapping it around the cone, moving downwards until you reach the base. The curve formed by the ribbon is a conical helix.

**Nadra Nittle**

Using the conical helix pattern, it’s helpful to look at a Christmas tree from the top while decorating it. Why is that?

**Dominik Czernia**

One of the aesthetic factors that please most people is uniformity. The best way to check it is to look at a Christmas tree from the top so you can see every single ornament on it. Do they look uniformly distributed from that point of view? Perfect! That’s what we’re aiming for. This is another unique feature of a conical helix; it gives us excellent uniformity.

**Nadra Nittle**

An efficiently decorated tree might even help cut down on electricity costs. That’s amazing.

**Dominik Czernia**

It surely could help. The larger number of lights naturally translates into higher power consumption. However, we don’t want to resign from the lights entirely; they’re one of those things which bring a magical Christmas atmosphere. What we can do, though, is plan in advance how bright our Christmas tree should be to buy light strands of appropriate length.

This allows us to avoid the situation in which the light strand is too long, and we hide it somewhere in the tree foliage or leave it trailing on the floor. But still, these redundant lights will use electricity and generate costs! A well-decorated tree has uniformly distributed lights around; thus, it looks as pretty as we wanted, and simultaneously, the length of strands is perfectly adjusted to the Christmas tree’s dimensions.

**Nadra Nittle**

Who’s the target audience for the Omni Calculator? Is it mostly math-and-science types, or have normies expressed interest?

**Mateusz Mucha**

Omni Calculator is used both by geeks and people who aren’t as confident with math, but it’s actually the latter group we think about the most. People have thousands of decisions to make that they should base on numbers. But they don’t think in terms of math formulas, don’t have the time, or just don’t feel like making this effort. And they end up making bad decisions. It’s our goal to make this process easy, fast, and kind of fun so that people are more likely to do the math.

**Nadra Nittle**

On the Omni Calculator site, there’s a funny gif of Monica from *Friends*. She turns a Christmas tree around to show off her expertly decorated side of the tree and to hide the very messy side her friends decorated. Do you think Monica would use your calculator?

**Mateusz Mucha**

Sure, but it’s actually Joey and Rachel who could get the most value out of it. Chandler suffers through Excel every day, so he’d be capable. Ross would somehow make the tree about dinosaurs, and Phoebe would try to save the tree and homeless squirrels instead.

## How to calculate the length of a Christmas tree garland using the formula and manually

Reading 3 min Views 16k. Posted by

British scientists were involved in decorating Christmas trees. It turns out that there is a simple formula that allows you to determine the ideal length of a garland for a Christmas tree. She was figured out by two students from the University of Sheffield in just a couple of hours.

According to their calculations, you can also accurately calculate the number of tinsel and Christmas balls. But let's dwell on the length of the garland: this is the most popular Christmas tree decoration, and also expensive. Following the advice, I got a cool lighting for an artificial Christmas tree, and now I don’t know the worries. And I won't know for a few more winters.

For calculations, you will need the exact height of the tree and the number Pi (it is equal to 3.14).

### Perfect garland formula

**0006 **

- 5 m (150 cm) x 3.14 = 4 m710 cm;
- 8 m x 3.14 = 5 m 652 cm;
- 2 m (200 cm) x 3.14 = 6 m 280 cm;
- 3 m (300 cm) x 3.14 = 9 m 420 cm;
- 4 m (400 cm) x 3.14 = 12 m 560 cm.

Gets the minimum length for an existing tree. Similarly, you can calculate the length of the lights for any height of spruce. Take measurements from the lower branches, not from the floor!

Tip

If the required length of the garland does not coincide with a round number, for example 6 m 280 cm, then choose a model of 6.5 or 7 m. It is better to buy decorations a couple of meters longer than to contemplate dim lights on three branches.

By the way, according to the length of the existing lighting, you can choose a new spruce, if you prefer a real, rather than an artificial tree every year.

### Length including the distance between the turns

When calculating, the width between the turns of the tape must also be taken into account. It will not be possible to name exactly your length with accuracy: 5-10 m will be enough for someone for a large spruce, and 15 will not be enough for someone. The best option is a step of 30 cm. To make the Christmas tree sparkle, choose a distance of 15-20 cm. For economical turns, we recommend placing no further than 40 cm from each other.

And now about the calculations. No mental effort is required, everything is already done for you. We find a site with a Christmas tree garland calculator and enter the desired data.

Here is an example of results for Christmas trees from 1 to 3 m high and 1 m in diameter. Data for LED type garland with 30 cm coils:

- for 1 m high spruce choose 10 m garland;
- for a 1.5-meter spruce, 10 m is also enough;
- for a height of 2 and 2.5 m we take 20 m;
- buy a 30 m garland for a three-meter Christmas tree;

The type of winding does not have to be helical. For example, there is an option to decorate only the front of the tree. And the garlands themselves are of different types. For them, calculations are also made with a calculator.
