Does anyone have any reference regarding this?

In the absence of a flurry of replies, possibly down to a risk assessment?

Stock signs (no links with them) https://www.stocksigns.c...osing-post-height-signs/ say 2.4m but don't give the reference.

Sorry, but I don't understand the question.  Can you rephrase it?

I would take it that the original post was referring to how high a sign that is protruding needs to be so as not to present a hazard. You could do a risk assessment, but I would think it is down to, dare I say it, common sense.

Depends upon several factors including:

The location of the sign - roadway, footpath, pedestrian excluded area etc.

The purpose of the sign - information or instruction

The intended recipient and their natural line of sight (including if transport related the usual/anticipated type of vehicle e.g. Go-kart/FLT/HGV/Quarry Vehicle)

(iii) Mounting heights

1.49 Where possible the lower edge of the sign should be between 900mm and 1500mm above the highest point of the carriageway alongside. The higher mounting should be used where excessive spray is likely to soil the signs. In built up areas signs may have to be higher for various reasons where they are erected on footways and transverse to them they must obviously allow sufficient clearance for pedestrians: 2100mm is the absolute minimum recommended but 2300mm is preferable.

Taken from Chapter 1 of the Traffic Signs Manual (TSRGD).  There is other information avaialble in the same chapter on distances from c/w edge etc.  There should also be reference in design justificaton documents where greater tolerances are required. 

Local Authorities will occasionally have some variances on these tolerances especially for cycle ways.  I remeber a height of 2.5m mentioned in one LA spec. 

Hope this helps

We obviously need more info. What is the purpose of the sign? This will inform you of its height, which should be just above anything that can hit it!

So, if the sign is inside on a corridor it needs to be a bit higher than the tallest possible person.

If it is in a car park a bit higher than the tallest allowable car. 

In a truck depot, a bit higher than the tallest truck.

You get the gist.
