Giant Advertising Balloons

Sizes in feet mean very little until you have something to compare them to. Here is what each one actually looks like next to things you know.

Spheres, 4.5 to 14 feet

A **4.5-foot** sphere is about the height of a kitchen counter stood on end. Small, cheap at $301, and genuinely useful for marking a spot people are already looking for.

A **7-foot** sphere is taller than a person and reads clearly from across a car park.

A **14-foot** sphere is wider than most single-storey buildings are tall. At $2,427 blank it is a serious object, and it needs 1,444 cubic feet of helium to fill.

Blimps, 10 to 30 feet

A **10-foot** blimp is roughly the length of a small car. $684 blank.

A **13-foot** blimp is about a mid-size car, and it is the size most buyers land on. $975 blank, $537 for lettering.

A **21-foot** blimp is longer than a delivery van. A **30-foot** blimp is longer than a bus, costs $6,772 blank, and takes 1,510 cubic feet of helium — over seven cylinders for one fill.

The comparison that actually matters

It is not size, it is how big the balloon looks from where your customer is.

A 13-foot blimp at 120 feet, seen from a quarter mile down the road, is about the size of your thumbnail at arm’s length. That is enough to notice and enough to read three bold words.

Going to 30 feet roughly doubles that apparent size. Flying higher instead makes it visible from roads it was completely hidden from. Height is usually the better lever, and it is free.

How to size it for your site

Do not start from feet. Drive your approach road and note where your building first becomes visible.

If that point is close because of trees or buildings, altitude is your fix and a 13 or 15 foot blimp is plenty. If you are on an open highway needing to be read from half a mile, that is where the 21, 25 and 30 foot blimps earn their keep.

Tell us the road and the distance and we will give you an honest answer, including when a smaller one will do.
