This has nothing to do with lace but I've seen this question answered before -
when I didn't need the info. I have a magazine with patterns printed at 50%
and 75% of full size. What size do I need to set a photocopier to get 100% of
pattern size?
Thank you.

The 50% has to be doubled (200%) The 75% has to be at 133% (I think) There
should be a formula for it, but I don't know what it is.
Clearly the 50% is half of what you want. The 75% needs to be increased by 1/3
of 75% in order for it to get to 100% lrb

Thank you Lynne
That makes sense to me. An answer many years ago used a formula which I didn't
understand. I'm going to save your answer for future reference.

I donât think that formula is right.
If you want to double the area (A5 -> A4) you have to use 141% on a
photocopier.
Thatâs because you increase the length by 141% and the length by 141%
1.41 x 1.41 = 2
1.41 is the square root of 2
Going on that, if you want to increase the area by one

Thanks Joy,
The last part, which I would call arithmetic, I can understand. I'm not going
to say how long it is since I studied maths but suffice it to say that it is so
long ago I've forgotten what it was about. I managed O grade maths, (algebra,
geometry, trigonometry) sat at 16, and that
I knew there had to be an equation. lrb
