You can search for info here or post new questions and comments at I am confused about how text works in terms of it's positioning and sizing with Inkscape becuase when i look in the code for the SVG it is giving me different values than in Inkscape.
For example i made a SVG test where the position of X: 0 in Inkscape but in the SVG code X: -6.9352403 and Y is also different.
I want to calculate the text area so i can scale the text with PHP and the test with a font size of 295.9022216796875px it gives me a area of Width: 744.090 and Height: 219.037 however if there is more characters it will be larger than the page area. How is the text Width and Height calculated?

Re: SVG text size and position confusion
Hi James,
It seems to be related to the font used. Probably the kerning of the font starts at x: -6.9352403 When I opened it in Inkscape on my Linux box the postion had move to -7.8 for Sans, whereas using Arial gave me a x: 0. The kerning of a font is taken from the font file itself and then passed to Inkscape. Changing the font to a somewhat better kerned one may do the trick for you.
A small tip. Rather than using the default A4, you might consider using a pixel based document size, such as 1024x768 or similar. Working in pixels can make things a lot easier and files more readable for later use with XML manipulation using PhP or javascript. Inkscape uses a 90 dpi resolution translation, so 1 mm is something like 3.45etc. pixels, making it rather hard to work from mm in scripts.
Cheers,
Jelle
