How much garland do you need?
Enter your measurements for the staircase, mantel, doorways, tree, and porch, and get the exact garland length, plus how many standard sections to buy. The drape is built in, so you won't end up with a thin run stretched tight.
How much garland to buy

Staircase / banister

Mantel

8 ft
Buy 4 standard 9-ft sections (32 ft needed). Garland always looks better slightly overfull than stretched tight, so this rounds up, and grabbing one extra section is cheap insurance against coming up short.
Now, what garland to buy
For which type to get (fresh vs. artificial, pre-lit vs. unlit, indoor vs. outdoor) by each location, see the Christmas wreaths & garland buying guide. Pre-lit warm-white is worth it on a mantel or staircase; battery-operated where there's no nearby outlet.
How the numbers work
The drape is the whole point. Garland has to be bought longer than the thing it covers so it swags instead of stretching flat. This calculator builds that in: railings get ×1.5, mantels get tails added down each side, wrapped posts get ×2, and a full tree spiral runs about 9 feet per foot of height.
The rules of thumb. Staircase/banister: railing length × 1.5. Mantel: width + ~3 ft of tail. Doorway/archway: ~18 ft to frame each. Tree: ~9 ft per foot of tree height for a full spiral. Porch post: height × 2 to spiral-wrap. Straight run (roofline, fence, shelf): length + 10% slack.
Round up, always.Garland reads as full and intentional when it's slightly overfull, and thin and sad when it's short. The tool rounds up to whole 9-foot sections; grabbing one extra is cheap insurance.
Then choose what to buy. Fresh vs. artificial, pre-lit vs. unlit, indoor vs. outdoor-rated. The wreaths & garland buying guide covers the right pick for each location.
Common questions
How much garland do I need for a staircase?
Measure the length of the railing you're covering, then buy about 1.5 times that length so the garland can drape in swags between the posts instead of stretching tight and flat. The draping is what makes it look full. For a standard flight of about 16 feet of railing, that's roughly 24 feet, or three standard 9-foot sections. Always round up; garland looks better slightly overfull than stretched thin.
How much garland do I need for a mantel?
Take the width of the mantel and add roughly 12-18 inches for each end so the garland tails down the sides, which comes to about your mantel width plus 3 feet total. A typical 5-foot mantel wants around 8 feet of garland. If you want a heavier, more cascading look with longer tails, add more. One full 9-foot section covers most mantels with room to spare.
How much garland do I need to wrap a Christmas tree?
Plan on roughly 9 feet of garland (or ribbon) per foot of tree height to spiral-wrap it from top to bottom, so a 7-foot tree takes around 60-65 feet, and a 9-foot tree around 80. That's a lot, which is why many people use garland in shorter accent swoops rather than a full continuous spiral. Decide which look you want before you buy: full spiral wrap needs the larger amount.
How much garland do I need to wrap a porch column?
To spiral-wrap a post or column, budget about twice the post's height in garland, so an 8-foot column takes roughly 16 feet. The tighter the spiral (the closer the wraps), the more you'll use, so round up. Use outdoor-rated garland for anything exposed, and secure it well against wind.
Why do I need more garland than the length I'm covering?
Because garland should drape, not stretch. Pulled tight across a mantel or down a banister, garland looks sparse and flat; bought longer (about 1.5× for railings, with tails on mantels, twice the height for wrapped posts) it swags and cascades, which reads as full and intentional. The single most common garland mistake is buying the exact length you measured and ending up with a thin, taut run.
Should I buy fresh or artificial garland?
Fresh garland smells wonderful and looks unbeatable but dries out in a few weeks and is an annual cost; artificial garland is a one-time buy that lasts for years, comes pre-lit if you want, and won't shed. A popular middle path is a quality artificial base refreshed each year with a few fresh sprigs or a new bow. For which type to get by location (pre-lit vs. unlit, indoor vs. outdoor-rated), see our Christmas wreaths and garland buying guide.
