Christmas Math: How Many Ornaments Should Go on My Tree?

“Math is everywhere,” they told us as kids as we huffed and puffed through concepts expressed through numbers, letters and symbols. “How does this apply to real life?” we wondered as we punched numbers into calculators that made graphs on tiny screens. Old World Christmas specializes in gorgeous hand-blown glass ornaments, not math, however one equation is important to us, and we believe that math ensures a beautiful Christmas. We believe that only math can answer the age-old question of how many lights and ornaments should go on each tree. 

Getting the Perfect Tree Picture

Math students from the University of Sheffield went where no man has gone before to research and test their Christmas decorating theories and to calculate the perfect Christmas tree to Christmas ornament ratio. The public was lost without this equation. How many ornaments are too many? How many lights are too few? Too many and the natural beauty of a sturdy Noble Fir is lost. Too few and tree swallows up the sparkle of the ornaments. 

Calculator Ornament

After extensive research and exhaustive study the students revealed the perfect formula. 6.2 ornaments per foot of Christmas tree is the most pleasing ratio of tree to ornament. For example for an average-sized five-foot tree, 31 ornaments, five strands of Christmas, 25 feet of tinsel (if you enjoy finding slivers of silver around the house in May), topped off with a tasteful 6-inch star would result in the correct amount, and most pleasing to the eye. For an easy cheat sheet broken down by the foot the ratio is as follows: 6.2 ornaments, 100 lights, and 5 feet of tinsel.

Christmas Tree with Presents Ornament

But, the equation doesn’t end the debate. Even on Old World Christmas’ staff, there are employees that stand by putting hundreds of ornaments on their tree. They decidedly do not adhere to the 6.2-ornaments-per-foot ratio. There are staff members with multiple trees to hold their extensive ornament collections. One unnamed employee hides half of her collection from her husband because they already have three Christmas trees beautifully decorated with the other half of her collection. 

Once the ratio is taken into account then the fun begins. Most people decorate their Christmas tree with their collection collected over years and years of celebrated Christmas seasons. Others choose a new theme each year or every few years. Many have multiple Christmas trees in their homes to express multiple themes. Maybe the kids get a small tree for all the homemade ornaments, the medium tree in the TV room with all the sports-team ornaments, and the grand tree in the living room with this year’s theme of travel or Santa or nature. If you're having trouble finding a theme, loot at our Christmas Ornament Sets for inspiration. 

Themed Christmas Trees

Decorating Christmas trees with ornaments is a nostalgic, exciting and special time recounting memories, relationships and events. There are no limits to the creativity and expression you can communicate through a Christmas tree. This year, as the holiday season quickly approaches, your tree can be a light, a reflection of beauty in a dark and challenging world. Considering the tree-to-ornament ratio might be a great starting point to this year’s gorgeous Christmas tree.

We recently subscribed to your on-line catalogue and are now busy finding new favorites. The text about how many ornaments should grace an area of a tree has us woefully over-ornamented. At last count several years ago, before we decorated the tree for the final time–it now stays up all year–we counted between 1,300 and 1,400 ornaments, icicles, along with 21 sets of lights on a 10-foot artificial tree. (Naturally, there’s also an assortment of Old World ornaments.) Still, I manage to purchase and place one or two ornaments each season, tho’ tree space has become a major challenge. Especially since we just found an entire catalogue to choose from. By the way, in keeping with America’s Christmas tradition, there are also several Lionel Trains and accessories running under the tree.

Thank you

A Christmas tree has enough ornaments when there isn’t room for any more. When you run out of room on the tree – put them on the garland over the fireplace.

Would love to share this “math” page to facebook.

I have 5 7.5 foot full trees , with hundreds of ornaments on each, about 80% Old World. The trees stay up all year, undecorated from mid-January to mid-November. Separate from the trees there are displays of most of the Cobane birds and a large number of ornaments from Slovakia and the Czech Republic. I am finally facing the fact that some ornaments will have to be retired from display, and I hope to find a museum that will display them each year.

I love having a formula for the ratio of ornament to Christmas tree, however when it comes to Christmas More is More!!! Let your tree sparkle with memories.
