ruler on screen at 100%

[behzad]

Hi, If I put a real ruler to the screen at 100%, it does not measure to the screen ruler. How can I get the screen ruler to
measure to an actual ruler. Take for example 11". On a real ruler it looks more like a 10 3/4"

Hi

could be your monitor screen doing that - if I put a ruler against mine it measures just under 11in, probably about 10 15/16ths

unless you have a special one, monitors are not that precise - quarter inch seems a lot, but if it's CRT with a lot of glass in front, or if you have polarising or anti-glare filters over it they may not be helping

[I'm assuming you run your monitor on native resolution]

It is HP w2007 and at 1680x1050 but your right, it may be how monitors are.

You will have to 'calibrate' your monitor.

Create a box 960 x 960 px with a Zoom Factor of 100%.
If your monitor is rendering 96 dpi, you might imagine you now have a box 10 inches (25.4 cm) square.

Measure it with a real ruler.

I got 8.8 in / 22.4 cm.
Divide this into 10 inches and you get a scaling factor of 1.13 or 113%.
Set 113% in your Xara application to get a one-to-one mapping.

On a second monitor, I measured 27 cm so i need to go to 94% for that one.

Perhaps we should have a content to discover who as a 100% monitor?

Interesting Acorn. It just seems too much work to do all that. I tried it in indesign and it looks fine without me changing any settings. I took the output from xara and measured it in indesign.

I don't believe 96 dpi is the default for all monitors. I just measured my Samsung (displaying a white raster) at 18 5/16" wide. It's native res'n is 1680 x 1050, and I calculate that to be very close to 92dpi.
