An organic balloon garland is built from three or four balloon sizes in the same colour family, inflated to slightly different sizes and clustered along a strip so nothing lines up. For a standard 3-metre garland you need roughly 30 × 12" balloons, 40 × 5" minis, 6–8 × 18" and one or two 36" giants. Inflate the 12s first, build the spine, then add the 18s and 36s for shape and finish with the 5s in the gaps. The rest of this guide is the detail: exact counts per metre, which sizes do what, and the order that stops the garland looking lumpy.
I've built hundreds of these for weddings, showers and shop openings, and the counts below are the ones I actually use — not a rule of thumb off a supplier's packet.
What sizes do you need for an organic balloon garland?
Four sizes, and they each do one job:
- 12" (30cm) — the body. Most of the garland is 12s, under-inflated to about 10–11" so they're rounder and easier to tie.
- 5" (12cm) — the filler. These go in last, pushed into every gap. They're what makes a garland look full instead of like a string of balloons.
- 18" (45cm) — the shape. A few 18s spaced unevenly along the line break the rhythm and make it look organic rather than uniform.
- 36" (90cm) — the statement. One or two giants, usually at one end or at the top of an arch, where you want the eye to land.
On longer arches and backdrops a 24" (60cm) is useful where an 18 looks small but a 36 would take over. For most garlands under 4 metres you won't need it.
How many balloons do I need per metre?
This is the table I work from. It assumes a full, "fat" organic garland about 40–50cm deep. For a slimmer garland, drop the 12" count by a third and keep everything else.
| Size | Per metre | 3m garland | 5m garland | Pack size |
|---|---|---|---|---|
| 12" (30cm) | 8–12 | 30 | 50 | 100 |
| 5" (12cm) | 10–15 | 40 | 65 | 100 |
| 18" (45cm) | 2–3 | 6–8 | 12 | 25 or 50 |
| 36" (90cm) | 1 per 2–3m | 1–2 | 2–3 | 2 or 10 |
In practice that means a 3-metre garland in one colour is one pack of 12s, one pack of 5s, one pack of 18s and one pack of 36s — with 12s and 5s left over for the next job. If you're mixing three colours, split those counts across the colours rather than buying a full pack of each size in each colour; the 5" minis are where you push in the second and third colour without it taking over.
Which colours work together?
Three colours plus one accent is the safe formula: a main colour (60% of the balloons), a supporting colour (30%), a third colour mostly in the 5" minis (10%), and a chrome every fifth or sixth balloon if the brief wants shine.
A few pairings I build again and again, all from the Stylex range so the shades match across every size:
- Boho neutral: White Sand, Coffee, Blush + Chrome Champagne
- Botanical: Hunter Green, Avocado Green (our sage), White Sand + Chrome Gold
- Baby shower: Baby Pink or Baby Blue, Pearl White, Pastel Dusk Cream
- Bold party: Hot Purple, Lime Green, Caribbean Blue + Chrome Silver
Browse the full range by family — pinks, greens, blues, neutrals, purples, reds, yellows — or order the Sample Bag (one 12" of every colour) if you're matching a client's swatch.
What order do you inflate and build in?
The order matters more than people think. This is the sequence that gives a smooth, full garland without going back to fix lumps.
- Inflate all the 12s first. Use an electric inflator with a sizer if you have one; aim for 10–11" and vary them a little on purpose. Tie them in pairs (two balloons knotted together), then twist two pairs into a cluster of four.
- Thread the clusters onto your strip or line. Garland tape (the plastic strip with holes) or fishing line both work; tape is faster, line gives a tighter garland. Push each cluster's knot through a hole and alternate the direction of each cluster so they interlock.
- Add the 18s. Inflate to about 16", tie in pairs, and tuck them into the spine at uneven intervals — every 40–60cm, never evenly spaced. Push them in from different angles so some face forward and some sit high.
- Place the 36. Inflate to 30–32" (a full 36" thins the latex and lightens the colour). Tie it with a long tail and secure it to the strip at the end or peak, then pull two or three 12s around it so it looks part of the garland rather than stuck on.
- Fill with 5s last. Inflate the minis to about 4" and use glue dots or low-temp glue to press them into every visible gap, especially where the strip shows. This is the step that turns "balloons on a string" into an organic garland.
- Hang it, then fix it. Mount the garland on the wall or frame first, then step back and add the last 5s and any 18s where it looks thin. Garlands always look different hung than on the floor.
How long does an organic balloon garland last?
Air-filled and indoors, a latex garland looks good for several days and often a week or more — it slowly loses a little size and shine as the latex breathes. Outdoors, heat and sun are the enemy: anything over about 30°C in direct sun will damage any latex balloon, and strong UV, wind and rain all shorten its life. For an outdoor event, install as late as you can, keep the garland in shade where possible, and keep a few spare inflated 5s and 12s in the car for touch-ups.
If the garland needs to float (a helium ceiling piece rather than a mounted garland), expect roughly 12–18 hours from untreated latex and treat the balloons with a float product for anything longer.
How do I order for a garland?
Everything above is stocked in every Stylex colour. Once you're logged in to a wholesale account, the Quick Order Form lists every colour across every size on one page, so you can type the counts from the table straight in. There's no minimum order, and orders in before 1pm Monday to Friday leave our Sydney warehouse the same day.
Quick answers
How many balloons for a 2-metre garland?
About 20 × 12", 25 × 5", 5 × 18" and one 36".
Can I make a garland with only 12" balloons?
You can, but it will look like a string of balloons. Even a handful of 5s in the gaps makes a big difference.
Do I need a pump?
For a 3-metre garland you're inflating 80-plus balloons, so yes — an electric inflator pays for itself on the first job. A dual-action hand pump will do the 5s and 260s.
Do the sizes match in colour?
At Stylex, yes — the same pigment runs through every size, which is the whole reason we started making our own range.
