Measuring the internal of a window

[ratchet]

I am repairing and replacing some wire screens for my windows

Is there a trick to measuring the inside cavity of a window to determine how long to cut the aluminium for a wire screen

I am using small plastic hings thingo , 2 mm each , two of them

I need clearance say 2 mm

How do I measure the inside of the window , to mm accuracy with a tape measure or some other thing

Can I put a pencil mark on the sill and measure with a meter steel rule from each end then add the two together

Yep, that will work. I generally measure from one side to a round number (say 800 if the window is roughly 900 wide) make a mark and measure back from teh other side and add the two figures together. If there's loads of this sort of measurement to make you could accurately cut a bit of timber at 100mm sit it in one side of the frame and measure to it from the other side.

Or just two short sticks and a C-clamp or two. No maths either way, and one less mistake to make.
