How Much Christmas Garland Do You Need for Stairs or a Mantelpiece?

It’s easy to measure a staircase rail or mantelpiece and still end up with a garland that doesn’t quite sit as you imagined. A gentle dip between banister posts, or a little greenery falling over each end of a shelf, uses more length than a straight run.

This guide shows you how much Christmas garland to allow for stairs or a mantelpiece. A piece of string makes the planning easier: follow the route you want the foliage to take, then measure the string before choosing a length.

Start with the route, not the straight-line width

Choose the points where the garland will start and finish. Lay string along the position you want it to follow, with the dips and end drops you actually like. Measure that string, then allow a little more at the ends for a secure attachment. Check the shaped width as well as the length: thick foliage can take up more handrail or shelf space than it appears to in a product photograph.

Product lengths are often given before the branches have been arranged. Do not stretch a short garland until the greenery looks thin or a fixing is under strain. If your planned route falls between available lengths, a slightly longer garland can sometimes be shaped back on itself; check the maker’s instructions before trimming or altering a wired stem.

For stairs, measure each dip

On a staircase, mark the places where you could securely attach the garland without covering the part of the handrail people grip. Run the string from fixing point to fixing point, letting it dip as deeply as you want the greenery to drape. Add the start and finish sections. Measuring only the sloping rail will underestimate the length if you want the garland to drape.

If one garland will not reach, measure the two sections separately and overlap their ends so the join still looks full. Secure each length in its own right rather than asking one join to hold both. Keep foliage, ties and any added light cable off the steps and out of the walking route. The staircase garland guide compares unlit designs and explains what to consider when putting them up.

For a mantelpiece, decide on the end drops

Measure the usable top of the shelf, then decide whether the garland should finish on the mantel or hang down one or both sides. Add those drops to the length that sits across the top, plus enough at the ends for attachment. For example, a 120cm shelf with a 30cm drop at each end already uses about 180cm before any extra for fixing or a loose curve. That is a planning example, not a standard length every mantel needs.

A full garland may also cover objects on the shelf or project past its front edge. Check the available depth and how you will secure it. If the fireplace or stove is used, keep decorations away from heat and follow the appliance’s clearance instructions; Scottish Fire and Rescue Service advises against decorations immediately above or around a fireplace. Choose another shelf if you cannot establish a safe position. Our mantelpiece garland guide covers shorter display options.

Check the length before ordering

Compare your string measurement with the exact length of the garland, noting whether a multi-pack contains separate strands. Check the attachment points and the space the foliage will occupy once opened out. If you plan to add lights to an unlit garland, measure the light-set route separately; its lead, battery box and connections need a suitable, unobtrusive place too.
