Overall, these lights transform any room, making it sparkle with warmth and holiday spirit, perfect for a joyful celebration.

How many Christmas lights do I need for my tree?

Here’s a festive rule of thumb to keep things glowing just right: aim for around 100 lights per 1 to 1.5 feet of tree height. That gives you a flexible starting point depending on how twinkly you want your tree to be.

For example, if you’re working with a 6ft tree:

• 400 lights will give you a subtle, minimalist sparkle—perfect for a pared-back Scandi vibe.
• 600 lights offers a balanced, classic glow that feels warm and welcoming.
• 800+ lights creates a dazzling, full-bodied shimmer that turns your tree into a true centrepiece.

Whether you’re going for understated elegance or full-on festive drama, the number of lights can completely transform the mood of your space.

And don’t stop at the tree—your garden deserves some sparkle too! We’ve rounded up the best outdoor Christmas lights to help you create a winter wonderland right outside your door. From twinkling icicle strands to colour-changing path markers, these picks will make your home shine from the street all season long.
