It is 30CM. After receiving the product, please open the box and you will see that the product is in a folded state. You need to manually break the branches apart to adjust the fluffiness of the tree.

They would look lovely for that application! But, they are not very wide. I went out to measure, and they are approximately 114 inches across visually at the midpoint of the tree, fully fluffed. So, you would need several to place them close together to get an effective partition.

Spreading the branches they are about 20" wide. We bought them as thin accents in our front porch vases then put seasonal plants around them. If you had many more they could hide something. They're a bit thin for privacy I feel.
