Measuring Lane Width

What is the official way to measure lane width?
Is it between markings or to centre line of markings?
Is cycle lane width measured from the kerb or is there a drain/gully allowance?
Thanks

That's a useful comment. Thanks
I also now now the answer to the other half:
Measurement is to the centre line of white line.

I can answer half the question. It is 'unobstructed' width, so grates etc. do not count as part of the width.
