Ninjakreborn Posted October 13, 2006 Share Posted October 13, 2006 I have a certain number of pixels, say I want to decide how many em's that is instead, is there a way for me to calculate that?

jcombs_31 Posted October 13, 2006 Share Posted October 13, 2006 what would be the point, they are different sets of measurements for a reason.

Ninjakreborn Posted October 13, 2006 Author Share Posted October 13, 2006 I have an image that is done in pixels, the photoshop file is in pixel's, I am trying my hand at a layout using mostly em's, the pictures have to remain closely the same sizes.

wildteen88 Posted October 13, 2006 Share Posted October 13, 2006 1em is about 16pixels. Link to comment https://forums.phpfreaks.com/topic/23857-calculating-the-difference-in-ems-and-pxs/#findComment-108404 Share on other sites More sharing options...
jcombs_31 Posted October 13, 2006 Share Posted October 13, 2006 If you are trying to make something pixel peferct, than use pixels, that's why they are a form of measurement. Use ems where appropriate. Link to comment https://forums.phpfreaks.com/topic/23857-calculating-the-difference-in-ems-and-pxs/#findComment-108449 Share on other sites More sharing options...
Daniel0 Posted October 13, 2006 Share Posted October 13, 2006 Use percentages instead. Link to comment https://forums.phpfreaks.com/topic/23857-calculating-the-difference-in-ems-and-pxs/#findComment-108465 Share on other sites More sharing options...

effigy Posted October 13, 2006 Share Posted October 13, 2006 An em is the size of the font, therefore it can change. A pixel does not. Link to comment https://forums.phpfreaks.com/topic/23857-calculating-the-difference-in-ems-and-pxs/#findComment-108580 Share on other sites More sharing options...

redbullmarky Posted October 13, 2006 Share Posted October 13, 2006 specifically, and hopefully to draw the curtains down, 'em' is the width (in pixels) of the letter 'M' (caps) for the particular font you're using, hence them name 'em'. so as stated by effigy, it changes with the font.[b]edit:[/b] in response to your post whilst i was typing mine - i've personally never used anything other than pixels and percentages. as for the others? i guess i'll know when to use them when i get to that stage.
