Seat clamp

[compo]

Seat clamps seem to come with a measurement (obviously). What I need to find out is is the stated size the size when fully compressed or the size when not compressed.

The seat tube on the bike I am doing up is 35mm, so would a 35mm clamp lock down properly?

If your tube is 35mm then then a 35mm clamp will be very slightly larger in diameter when undone and smaller in diameter when bolted or clamped up. What the actual range is I can't say without measuring one.......

So the answer to your question is yes
