Flagpole heights in Ireland: common heights and planning
Published Written by Flagpole Guides
The height of a flagpole decides how far the flag can be seen, how large a flag it can carry, how much wind it has to withstand and how big a foundation it needs. In Ireland, flagpoles are usually sold in whole metres, from short wall-mounted poles of about 2 metres to poles of 10 to 12 metres for public buildings, and taller on request.
Common heights
| Height | Typical use | Flag size according to an Irish supplier |
|---|---|---|
| 2–3 m | Wall-mounted poles, small gardens | 900 × 1800 mm |
| 4–5 m | Gardens, small clubs | 900 × 1800 mm |
| 6–7 m | Homes, schools, clubs, businesses | 900 × 1800 mm |
| 8–9 m | Business parks, larger schools, hotels | 1200 × 2400 mm |
| 10–12 m | Public buildings, large sites | 1500 × 3000 mm |
The flag sizes come from the flag size guideline of FlagPoles Ireland, a Dublin supplier and installer. The flag size calculator shows the size for each height.
Why 6 metres
FlagPoles Ireland starts its range of vertical poles at 6 metres, or about 18 to 19 feet, and calls it the standard height. The reason it gives: when the flag is not flying, it hangs down the pole, and on a shorter pole the bottom of the flag may be within reach from the ground, where it may be vandalised, especially if it is a flag of political concern.
Height and the National Flag
According to the guidelines of the Department of the Taoiseach, when the tricolour flies with the flags of other nations, each flag flies from a separate pole of the same height. If one pole is higher than the rest, the National Flag is flown from that pole. For a site that flies the tricolour next to a company or club flag, the same principle applies: nothing is flown above the National Flag. More in the guide to flag protocol.
Spacing
FlagPoles Ireland recommends that flagpoles stand at least 2 metres apart, so that the flags do not touch the pole beside them. With larger flags, the spacing grows with the length of the flag.
Height and planning
Irish planning rules have no height limit specific to private flagpoles, because there is no specific exemption for them. In 2012 the Minister of State told the Dáil that all development needs planning permission unless exempted, that there are exemptions for flags and flagpoles of statutory undertakers and State authorities, but no specific exemption for flagpoles erected by individuals. A taller pole is more visible and more likely to affect neighbours and the streetscape; whether a particular pole needs permission is for the council to decide. The process is described in the guide to installing a flagpole.
Height and foundations
A taller pole carries a larger flag and more wind, so the foundation grows with the height. FlagPoles Ireland suggests foundations from 300 × 300 × 500 mm for a 4-metre pole to 600 × 600 × 900 mm for a 10-metre pole. The actual size depends on the pole, the soil and the manufacturer’s instructions.
Height and power lines
The higher the pole, the further it reaches when it is carried, raised or lowered. ESB Networks states that no construction activity takes place within 10 metres of an overhead electricity wire, and that anyone planning to work near overhead wires contacts ESB Networks first. More in the guide to flagpole safety.
Measuring height
Flagpole heights are usually given as the height above ground of the finished pole. A sleeved or hinged pole may have part of its length in the foundation, and a finial or truck adds a little at the top. The types of pole are compared in the guide to types of flagpoles.
Frequently asked questions
What is the standard height of a flagpole in Ireland?
An Irish supplier, FlagPoles Ireland, calls 6 metres (about 18 to 19 feet) the standard height and starts its range of vertical poles there, so that the bottom of a hanging flag is out of reach from the ground.
Is there a height limit for flagpoles in Ireland?
There is no height limit specific to flagpoles in the planning rules, because private flagpoles have no specific exemption. Whether a particular pole needs planning permission depends on the site and the council; a section 5 declaration settles the question.
How far apart are flagpoles placed?
FlagPoles Ireland recommends at least 2 metres between flagpoles, so that each flag can fly without touching the pole beside it.
Does the Irish flag go on the tallest pole?
According to the guidelines of the Department of the Taoiseach, flags of different nations fly from poles of the same height. If one pole in a group happens to be higher, the National Flag is flown from it.
