Bunting Measurements Checklist: Flag Size, Spacing, and Drop Length

Bunting looks like the simplest decoration in the box until you have cut forty flags and worked out that the string is two feet short of the wall. Almost every bunting problem traces back to one of four numbers: flag width, the gap between flags, the total length of the run, and the drop. Get those right on paper first and the sewing, stapling or tying takes care of itself.

This is the checklist to run through before you cut anything. It suits fabric bunting, paper flags, card triangles and ready-made strings alike.

Measure the Space Before You Choose Anything

The measurement that matters is the length of the line the bunting will actually follow, not the width of the room. Those are rarely the same. Bunting hung in a shallow curve is longer than the same bunting pulled tight between two hooks, and bunting dipping under a beam is longer again.

Run a length of string or ribbon along the route you want, following every curve and corner, then measure the string. Note three things while you are up there:

• Span — the distance between the two end fixing points, measured along the hanging line.
• Fixing heights — how far each anchor point sits from the floor. If one end is higher than the other, account for the slope.
• The lowest point of the flags — the spot where bunting might meet a head, a doorway, a table or a candles-topped cake.

Write these down. Guessing from memory is how people end up with a run that sags into a walkway.

Flag Width and Gap: The Two Numbers That Set the Look

Wider flags read from further away. Narrow flags suit close-up work. As a working guide, use 6–8 in (15–20 cm) wide flags for table fronts, shelves, small rooms and doorways, and 8–10 in (20–25 cm) for party walls, gardens, halls and marquees. Below about 5 in, a flag stops reading as a flag and starts reading as trim.

For gaps, half the flag width is the safe default. An 8 in flag with a 4 in gap looks balanced and traditional. Two variations are worth knowing:

• Airy and modern: gap equal to the flag width. Fewer flags, more wall showing, cheaper on fabric.
• Dense and bold: gaps of 1–2 in. Good for photo backdrops and anywhere the bunting should feel solid rather than scattered.

Measure the gap from the edge of one flag to the edge of the next, and keep it identical all the way along. If you are sewing double-sided flags, add a seam allowance of around 3/8 in (1 cm) to each edge when you cut — but plan your spacing from the finished width, not the cut width.

Working Out Total Length

Total length is a three-part sum: flags, gaps and tie ends. The tie ends are the part people forget. Allow 12–18 in at each end for knotting, looping over a hook or wrapping a pole — more if you are tying around something thick.

Here is the calculation in practice. Say the span is 12 ft (144 in), with 8 in flags and 4 in gaps. Set aside 18 in at each end, which leaves 108 in. Each flag plus its gap takes 12 in, so 108 ÷ 12 gives you 9 flags. If the run will swag rather than sit taut, add roughly 15% to that 108 in figure: about 124 in, which rounds to 10 flags at 120 in with a little slack to play with.

Deep swags need more than 15%. For a pronounced dip, mock the curve up with a spare string and measure it — guessing at a deep swag is how you run short at the last hook. And when you are tying to fixed points, round the flag count down rather than up. You can always space flags slightly wider, but you cannot compress a tight run of fabric.

Drop Length and Hanging Height

Drop is how far the flag hangs — the depth of a triangle, or the height of a rectangle. Triangular bunting usually works well with a drop roughly equal to the flag width, or slightly more; an 8 in wide triangle with an 8–10 in drop looks right. Longer, thinner triangles look elegant indoors but catch the wind outside and hold water when damp.

For hanging height, work from the bottom up. Where people walk beneath the bunting, keep the lowest point at 6 ft 6 in (about 2 m) or above; 7 ft is safer for a busy route. Then check the arithmetic: if a doorway frame top sits at 6 ft 8 in and your flags have a 10 in drop, the flags finish around 5 ft 10 in — fine to look at, too low to walk through. Either shorten the drop, or run the bunting across the wall beside the opening instead.

Other common heights:

• Photo backdrop: fix at 6–7 ft, with flags hanging down 5–6 ft.
• Above a cake or buffet table: bottom edge around 5–6 ft so it frames the table without crowding it.
• Table front: top edge at the tabletop or just under it, dropping as far as you like — these are decorative, not overhead.

The Checklist

Take this with you to the room, the garden or the venue:

• Span measured along the actual hanging curve
• Height of each fixing point from the floor
• Lowest point of the flags, and clearance for anyone walking under
• Finished flag width and drop
• Gap between flags, identical all along
• Number of flags = available length ÷ (flag width + gap)
• Tie allowance: 12–18 in per end
• Extra allowance for swags: around 15% for gentle curves, more for deep ones
• Total tape length = flags + gaps + ties + swag

Test With Paper First

Cut four or five paper flags at your chosen size, tape them to a length of string at your chosen gap, and pin the whole thing up where it will hang. Stand where your guests will actually stand and look at it. This five-minute rehearsal catches more mistakes than any calculation — the gap that seemed generous on paper often looks mean on a big wall, and the drop you liked on a table can suddenly sit at eye level.

Final Checks Before You Tie Anything Off

Lay the finished bunting out on the floor and measure it end to end before it goes up. Confirm the flag count, the gaps and the tie ends all still match your notes. Check that the tape is strong enough for the weight once the flags are on it, particularly outdoors where damp fabric gets heavy and wind adds strain — and that whatever you are fixing to can take a gentle repeated tug.

If the numbers are right, hanging takes minutes and stays put. If they are wrong, you find out in front of everyone. Measure twice, cut once, and let the bunting do the rest of the talking.
