So, you’ve just installed your brand-new Outdoor Flagpole in front of your building or home. The excitement and anticipation build as you unpack your Outdoor American Flag and get ready to attach it to the flag snap hooks and hoist it up the pole. But wait – is your flag the right size for the pole?

If you purchased your flagpole from LIBERTY FLAGS, The American Wave®, it was delivered with an appropriately sized flag, but if not... here is a quick guide to selecting the correct size flag for your flagpole.

Residential Flagpoles

Whether you are displaying your American Flag from your house-mount flagpole or your ground-mount residential flagpole that is 20' or shorter, it’s advised to fly a 3’x5’ flag at the largest. This is the perfect size to show your patriotic pride in front of your home. If your permanent residential flagpole is taller than 20' please keep reading for Commercial Flagpole guidelines.

Commercial Flagpoles

Commercial Flagpoles are designed for long-term or permanent use. They are also designed to fly larger flags, depending on the type, height, and wind rating of the flagpole. The basic rule here is that the horizontal length of the flag should be roughly 1/4 the height of the flagpole. This guideline applies to commercially-manufactured flagpoles 20’ to about 80', but it is always advisable to consult the manufacturer's recommendation.

Flying Two Flags?

Flying two flags is no problem. The primary flag size stays the same. The secondary flag will be one size smaller than the primary flag.

Of course, for Ambassador, Embassy, Skyscape, Landmark, and Pioneer flagpole models, a second flag will require a second set of snap hooks.

Empire flagpoles will require a second set of snap hooks, plus a quick link, a cable swivel, and a correctly-sized flag arrangement.


One of the most important things to consider in terms of safety and flagpole longevity is windspeed. Depending on the season and the region in which you live, windspeed will obviously vary. Download our handy windspeed map to get a better understanding of possible wind speeds in your area.
