You could always work it out;

Diameter = 2 x (sq rt of(area / pi))

obviously, that will be the diameter of a single conductor; not the cable.

Draka do a book which they send out free, which is online in the link I have given.

The tech specs are all in there. About page 100 for 'general cables'.

FS Cables also do a similar book which they send out free, which also includes more specialist cables.

Well perhaps it time to use a bit of common and ingenuity, get a piece of 6 " x 2" 3mm thick plastic cut a narrow V down it with a band saw and using scrap cable slide them down and mark off where they end, a simple V gauge.

6" x 2" x 3mm?

That sums up half the problems in dealing with LABC Inspectors...

The TLC site has cable diameters. For example at the top left:

well if you are going to all that hassle - sorry common sense - of making a superflous gauge why not just measure the cable with a ruler?

Ruler? a micrometer would be more appropriate i'd say,

As Dave has said, a micrometer is all that is needed, plus manufacturer's data, such as Prysmian/Delta.

I liked Rocks measures.
Like me he is bi-lateral in his thinking even though his famous saying is
"We must go metric every inch of the way!".
that 6" x 2" x 3mm works out costing less than 13s 7d per square inch if you buy it in 4 metre lengths too.

A micrometer or a hernia kaliper or "rack of eye" are also useful just like the V

2.5 1.7841 0.0702 2/29

4.0 0.853 (7 Strands) 0.0336 3/89

Now you have the means of determining sizes from tables, plastic vernier scales are available, and should be OK up to 400V. Also, a box of samples is useful , by collecting over the years.
