Information on flag size

The correct flag size in relation to the flagpole length

A correctly sized flag is crucial for a harmonious overall appearance and the longevity of the entire flag system . Whether in a private garden, in front of company buildings, or at club grounds – the right flag size ensures that a flag can achieve its full effect without putting unnecessary strain on the flagpole.

Why the right size is so important

Flags that are too small lose their impact . On a tall flagpole, they quickly appear lost; the proportions are off , and from a distance, the flag is barely recognizable . The overall impression is unbalanced and unrepresentative .

However , excessively large flags can put significantly more strain on the flagpole. Especially in strong winds, this creates increased tensile force , which – depending on the pole's material – can lead to faster wear, damage, or in extreme cases, even pole breakage.

Aluminium and GRP masts are particularly sensitive to wind, while wood reacts somewhat more flexibly, but should also not be subjected to excessive stress.

Conclusion

Choosing the right flag size isn't just about looks, but also about safety and durability. Following the one-third rule of flag etiquette will help you select a flag that looks stylish while also providing optimal protection for your flagpole.
