How Many Christmas Lights Do I Need?
There is nothing quite as disappointing as reaching the top of your Christmas tree only to discover that your lights will not stretch any further. Use too few and the finished tree can look sparse; use too many and the decorations may disappear beneath the glow.
So, how many Christmas lights do you really need?
As a starting point, we recommend using at least 100 lights for every 2ft of tree. If you prefer a brighter and fuller display, aim for approximately 100 lights per foot.
However, the perfect number also depends on the width of your tree, the type of lights you choose and how brightly you would like it to shine.
How many lights do I need for my Christmas tree?
Use this guide as a starting point:
| Tree height | Subtle glow | Bright, fuller display |
|---|---|---|
| 2ft to 3ft | 100 lights | 200 to 300 lights |
| 4ft | 200 lights | 400 lights |
| 5ft | 250 to 300 lights | 500 lights |
| 6ft | 300 to 400 lights | 600 to 750 lights |
| 7ft | 400 to 500 lights | 750 to 1,000 lights |
| 8ft | 500 to 750 lights | 1,000 to 1,500 lights |
| 9ft | 750 to 1,000 lights | 1,500 lights or more |
These figures are only a guide. A slim tree may need fewer lights, while a wide or densely branched tree will usually need more.
Cluster and compact lights also position the bulbs closer together than traditional string lights, creating a much fuller effect without necessarily covering a greater length of the tree.

Does the width of the tree make a difference?
Yes. Two trees of the same height can require very different numbers of lights.
A full, traditional tree has longer branches and a greater surface area to cover. If you want the lights to travel towards the trunk as well as around the outer branches, you will need a longer set with more LEDs.
A slim Christmas tree has a smaller circumference and can usually be covered with fewer lights.

When choosing your lights, consider:
-
The height of the tree
-
The width at its broadest point
-
How densely packed the branches are
-
Whether you will light only the outside or work into the inner branches
-
Whether you prefer a subtle or highly illuminated effect
If you are unsure, it is usually better to have slightly more lights than you think you need. Extra cable can be worked further into the branches, but it is difficult to disguise a large unlit gap.
Traditional, compact or cluster lights?
The number of lights is important, but the style you choose will have an equally big effect on the finished appearance.

Traditional string lights
Traditional string lights have more space between each bulb. They are easy to arrange and offer plenty of flexibility for trees, garlands, windows and other festive displays.
They are a good choice if you prefer a softer glow or want to combine your lights with a large collection of decorations.
Our Premier multi-action Christmas lights are available in a choice of LED quantities and colours, making it easier to find a set to suit trees of different sizes.
Compact Christmas lights
Compact lights have smaller spaces between the LEDs, creating a denser and more evenly illuminated finish than a traditional string.
They are ideal for anyone who wants plenty of lights without the heavily layered appearance of cluster lighting.
Our Lumineo compact lights include sets of 750 and 1,500 LEDs in colours including classic warm, cool white, multicoloured, soft multicoloured and warm-and-cool white.
Cluster Christmas lights
Cluster lights position a very large number of LEDs close together along the cable. This creates a rich, sparkling effect with fewer visible dark spaces.
They are a particularly good choice for creating a showstopping tree or adding plenty of festive impact with one set of lights.
Our Lumineo and Premier cluster lights range from approximately 700 LEDs to impressive 3,000 LED sets.
Because the LEDs are grouped closely together, cluster lights will appear much brighter and fuller than a traditional light set containing a similar number of bulbs.

What colour Christmas lights should I choose?
The right colour depends on the style of your tree and decorations.

Classic warm and warm white
Warm lights create a welcoming, traditional glow and work beautifully with green Christmas trees, natural materials, red decorations and gold baubles.
Classic warm lights usually have a richer golden tone, while warm white offers a softer and slightly more neutral finish.
Soft gold
Soft-gold lights create an elegant glow that complements champagne, bronze, gold and natural decorating schemes.
They are a lovely choice if you want something warmer than standard white without a strongly yellow appearance.
Cool white
Cool-white lights have a crisp, icy appearance. They work particularly well with snowy and frosted trees or decorations in white, silver and blue.
Multicoloured and rainbow
Multicoloured lights create a cheerful, nostalgic display. They are ideal for family trees filled with colourful decorations or anyone who enjoys a fun and playful Christmas look.
Soft-multicoloured lights provide a gentler alternative, while rainbow lights produce a brighter and more contemporary effect.
Warm and cool white
Cannot decide between warm and cool white? A combined set gives you greater flexibility and can complement a wider variety of decorating styles.

Should I choose a green or clear cable?
The cable colour may seem like a small detail, but choosing the right one will help it blend into your display.
A green cable is usually the best choice for a traditional green Christmas tree because it disappears among the foliage.
A clear cable works well with snowy or heavily frosted trees. It is also useful when decorating pale surfaces, windows or light-coloured garlands.
Do pre-lit Christmas trees need extra lights?
A pre-lit tree is designed to create a complete illuminated display without needing an additional set.
However, you can add more lights if you would like to introduce another colour or create an even brighter effect. Check that the additional lights are suitable for the intended location and avoid overloading plugs or extension leads.
Our pre-lit artificial Christmas tree collection includes designs with traditional LEDs, delicate micro LEDs and colourful nostalgic-style lights.

Can I use Christmas tree lights outdoors?
Only use lights outdoors if the packaging or product information clearly states that they are suitable for outdoor use.
Keep plugs, transformers and connections protected from wet weather. A weatherproof connection box can help protect compatible plugs and transformers when creating an outdoor display.
Always follow the instructions supplied with your lights and check the cable for damage before use.

How many lights do I need for a 6ft tree?
For a gentle glow, approximately 300 to 400 traditional lights should be enough for an average 6ft tree.
For a brighter and more evenly illuminated appearance, consider between 600 and 750 lights. A wide or particularly full tree may benefit from more.
How many lights do I need for a 7ft tree?
We recommend approximately 400 to 500 lights for a subtle display on an average 7ft tree.
For a fuller, brighter effect, choose a set containing approximately 750 to 1,000 lights. If you are using closely spaced cluster lights, the finished result will be especially rich and sparkling.
How many lights do I need for an 8ft tree?
An 8ft tree will generally need at least 500 to 750 lights. For a full and highly illuminated display, consider between 1,000 and 1,500 lights.
Remember to account for the width of the tree as well as its height.
Can a Christmas tree have too many lights?
There is no single maximum number, as the finished effect is a matter of personal preference.
However, very densely arranged lights can overpower your decorations and make the individual baubles more difficult to see. They may also create unnecessary lengths of cable among the branches.
If your decorations are the main feature, choose a softer glow. If you want the tree itself to sparkle from across the room, compact or cluster lights will create a more dramatic finish.
