How much longer is the coast of Great Britain when the tide is out?

Not a lot.
High tide on east coast lower tide on west.

Assuming the inlets where the tide going out shortens the coast by a similar amount to peninsulas where it increases then we could assume the coast to be roughly oval. Next if we assume the tide goes out by an average of 25m to account for cliffs with nothing and tidal flats which stretch for miles the expansion would be under 100m.
In places you might even find the coastline is shorted when the tide goes out as you replace a rocky area with lots of bumps with a nice smooth sandbank.

The coastline is a fractal which means it is infinitely long.

The coastline is a fractal which means it is infinitely long. I watched Overcoming and it seemed infinitely long.

Of course it's not infinitely long if you measure it with a defined unit. Given that the original comment was regarding walking perhaps we should consider it's length when measured to the nearest foot.
