Pick a suitable size

Once you’ve decided on a shape, it’s time to think about the size of flag you want to use.

Consider the environment you will be working in, whether it’s indoors or outdoors and think about the impact and attention you want to attract using flags.

Our advertising flags come in a range of sizes:

Size reference Feather shape Teardrop shape Crest shape
Small 2600mm 2100mm 2600mm
Medium 3200mm 2800mm 3200mm

Match your flag to a suitable base

There’s a variety of flag bases to choose from depending on the type of flag you have. When choosing a flag base, it’s best to split out the options based on indoor or outdoor use:

For indoor flags:

Crossbases are the popular choice for indoor flags. Small or large crossbases fit small and medium or large and extra large flags respectively.

A slightly sturdier option is the 400mm weighted square base. This base has a larger surface area and so, is heavier too weighing in at 4 kilograms.

For any indoor event where a car is parked next to your event set up, or is the focal point of your display, then a drive on foot is perfect. As the name suggests, you simply park one tyre over the drive on foot to keep the flag securely standing.

Indoor flag bases

For outdoor flags:

Crossbases partnered with a weighted ring adds enough stability to allow your flags to be used outdoors. The weighted ring is water or sand fillable with a capacity of approximately 6 litres.

Is your outdoor event on soft ground outdoors? Ground spikes will securely anchor into soft ground in fields.

Other outdoor flag bases include: large water bases, water bases with feet and concrete bases.


  1. Decide the shape of flag you want to display. The artwork you want to use should help decide on the shape of flag that works best.
  2. Pick a suitable size that suits the environment you will be displaying the flag in. Don’t go too large if your event is indoors – will there be height restrictions? If outdoors, you may want to go for the larger sizes to easily attract attention.
  3. Match your flag to a suitable base. Once decided where your flag will be displayed, pick a suitable base that will keep you flag anchored to the ground all day long.
