You need to pick a flag based on what your pole is engineered to
withstand. Only the manufacturer or supplier of the pole knows what the
recommended size is for a certain model. We can only tell the recommended
flag size for a pole we sell or can otherwise identify by model number and
manufacturer. And even then, a recommended flag size does
not mean that flags can be flown in all conditions without damage to the
pole. When bad storms are expected you should remove your flags .
If a pole is not known to us we have no way of knowing what size flag it can
take and can make no particular recommendation. It is not enough for us to
know that you have a "really big" pole. Some companies like to
tell you that a 30' pole takes a 5x8' flag or a 25' pole takes a 4x6'
flag. I have never understood why anyone would rely on that kind of
advice. Would that be a 30' pole with a 6" diameter, or a 30 pole with a
3" diameter? Is it a 30' modern commercial pole or is it an ancient home
made 30' pole? What is it made of? What is the wall thickness? What is the
condition? See what we mean? Knowing a pole's height is not enough.
The larger the flag on any pole, the more stress on that pole.
We always suggest a smaller flag rather than a larger flag. Also know
that heavy polyester flags are said to stress poles more than nylon flags
especially when they are wet.
Flying more than one flag on a pole increases the stress on it. For the
poles we sell, we will always tell what the
recommended size is for a single flag. We will suggest that only one flag be
put on a pole. But knowing that many people will fly more than one flag
on a pole tell them:
"If you're going to fly more than one flag, do it with your eyes wide
open. Decrease the size of your flags so as not to exceed the total square footage of flag load as recommended by the
manufacturer. And if you get storms, remove your flags. The greater the
flag load, the greater the chance that you can break your pole
People sometimes ask us if a pole can break. We make the point that any pole can break. A common way I put it is to
say:
"Any pole can break. If you get enough wind anything can break. Your
house can blow down, telephone poles can break, big trees can break. If your car axle can break, your pole can break. We caution you to
do whatever you can to protect your pole. The main way you can do so
is to fly the recommended flag size. Unless we know the exact model number of a pole we sell, we can not
recommend a size.
If someone tells us the size of their pole, we only say what is
commonly flown on that size pole. Look at the charts on our flagpole pages
and you will see what poles of ours take what size flags But we say at the same time that we do
not know if your pole can take that size flag.
Flag sizes do not constitute a warranty that flags of the size shown may
be safely flown in all winds. Remember that wind gusts can be greater than
a storm's prevailing winds. Flying greater flag loads or flying them in
higher winds than rated may result in damage to the pole. Flags should be
removed from any pole long before winds reach the wind speeds shown.
There is a rule of thumb commonly quoted if the flag industry saying
that the length of a flag is about 1/4 the length of a pole. We do not
offer this as advice on what any given pole is meant to take. If we point out that a pole we sell, which you say is similar to the
specs of your pole, takes a certain size, that does not mean that your
pole takes that size. We don't know your pole. You do. We will supply you with any flag size you tell us. That is in no way to
be understood that we endorse that size to be proper for your pole. It
means that you are telling us it is the flag you say is fit for you to
fly.
Sometimes people return a flag and say we "sold them the wrong size."
On the contrary, we never "sell" anyone on any particular size. We point
out our sizes, the customer chooses, and we hand them a flag. They pick.
We supply. It is very common for people to greatly err on their own flag
pole size. We've seen someone claim they have a 40' pole and have it turn
out to be 15'! Yep, it happens. Also, people are often reluctant to simply measure the
flag already flying on their pole. Instead they prefer to guess. Or they tell
us what is a "proper" size for whatever they guess the height of their
pole to be. We never tell them any "proper" size. Instead, we tell them
all the above information.
Unless we know your pole, we can not reliably tell you what the
recommended flag size is.
