Inflatable Festival Sculptures: Large Shapes on Open Sites
On an open festival site the competition is a horizon, not a neighbouring stand. Pieces at this scale are bought to be seen from the far side of a field, and almost everything difficult about them follows from the size rather than from the shape.
Planning references put festival-scale pieces at 3–10 m high, and that figure is the smallest of the problems it creates. Packed volume and weight rise with surface area, so freight is quoted by volume rather than by the headline height; the crew and the install window lengthen; and the ground it stands on has to be assessed rather than assumed.
Design gets simpler as the piece gets bigger, not more elaborate. At the distance these are viewed from, the silhouette does the work and surface detail disappears, so the review before production is mostly about whether the outline still reads — and about removing detail that will cost money and never be seen.
Festival-scale pieces run larger than any other application on this site.
Crew, install window and packed volume grow faster than the height does.
Detail that reads at three metres is invisible at ten; the design is reviewed for it.

What a quotation for this format is built from.
Sizes buyers usually order
A custom shape is sized by the site. As planning references from delivered project types: forecourts, race routes and trade show stands are commonly 2–5 m high, shopping mall and seasonal displays 2–6 m high, festival-scale pieces 3–10 m high, and walk-through tunnels 5–15 m long × 3–6 m wide × 3–5 m internal height.
Send the constraint rather than the wish. A ceiling height, a doorway, a stand footprint, a truck bed or a rigging point fixes the size far more reliably than a target figure does, and it is what the manufacturer works back from when the two disagree.
What a shape has to be before it can be quoted
A custom shape needs a reference the manufacturer can build a pattern from: dimensioned drawings, photographs from several angles, a 3D file, or the physical object itself. A single flat illustration is a starting point for a conversation, not something a pattern can be cut from.
The more organic the shape, the more it changes under pressure. Sharp corners soften, thin sections thicken, and undercuts either need internal structure or disappear. The production drawing shows every one of those adjustments before anything is cut, and that drawing — not the original illustration — is what you are approving.
Material and air system
Double-layer PVC is the general construction. 0.4 mm PVC is used on large-format projects, and 0.5 / 0.6 / 0.7 mm PVC mesh where the structure carries load, spans further or faces sustained exposure.
The air system is sized to the piece: the 650 W electric pump moves 1,600–2,000 L/min at 2.0 psi and suits smaller spheres, compact displays and short-duration indoor installations; the 1600 W electric pump moves 4,800–5,200 L/min at 4.5 psi for large-format structures, arches and continuously inflated outdoor displays. Both run on 110–240 V, 50–60 Hz, and the destination plug type is confirmed on the order.
Standing, spanning or suspended
How a piece is supported changes how it is built. A ground-standing shape needs a base and ballast sized to its own footprint; a piece people walk through needs clear internal dimensions and a structure that holds them; a suspended piece needs attachment points designed into the seams with the load spread across them.
Decide this at the brief stage. Where a piece is to hang, the venue confirms rigging points and load per point before the size is fixed, because a shape that cannot be hung where you need it is a shape that has to be rebuilt.
Lead time, quantity and freight
MOQ is 1 piece for most custom projects, so a single piece can be approved before a repeat order. Pattern and print setup are paid once per design, so a second unit costs less per piece than the first.
Bulk production typically takes 3–8 days for simple items, 7–15 days for standard custom work and 15–25 days for complex or large pieces, counted from final design approval. Freight comes on top: express or air usually 4–15 working days, and sea, rail or truck usually 20–45 days, after dispatch and subject to route and customs
Request a Quote for an Inflatable Festival Sculpture
Send the shape reference — drawings, photographs from several angles or a 3D file — the size or the constraint that fixes it, the quantity, the destination and the date it has to be on site.
Start with four essentials: product type, rough size, quantity, and one way to contact you.
Country, timing, artwork, and technical details are optional at this stage. We will request anything else needed for a usable factory quote.
