Tin shed sizes?

[Kidds]

What determines the size of new sheds?
They all seem to be measured in feet, is there a reason for this?
I'm asking because I want to build a new Dutch barn and lean to. I would like it to be 15m x 10m overall footprint. This is based on an old one I have measured up, it has 3 x 15'6" bays giving 14.17m. Any reason I can't have 5m bays?
All I can think of is available timber length of 4.8m or that it wouldn't fit the sheets most economically.

Any thoughts appreciated.

5m bays would be possible. Some people go up to 20’/6m bays with big enough timber or z purlins.

When you say Dutch barn are you hoping to build the new one with a curved top or you going for a pitched roof?

Plus I think you’ll be shocked at the size of steel for the columns that is speced nowadays compared to the excisting one!!

Traditionally bay sizes are 15 or 20ft, one reason for this could be sheet sizes, eg big six is 40 inch cover.

Yes, curved roof was the plan

15ft and 20ft bays just seem to be the norm on cattle building now, timbers come in these lengths and also fibre cement roof sheets cover 1016mm so are perfect for 20ft bays.

Many industrial buildings are now built with 8m bays

5m is a good size for bays forstraw
15ft or 20ft are an awkward size for hesstons

The use of feet & inched is mostly just historical custom & farmers mostly think in terms of those units, whereas in industrial/commercial there's more usage of metric.

Even though sizes are usually referred to in terms of feet & inches, the chances are it will be built to the metric equivalents anyway.
