I'm trying to calculate the width of an HTML element based on the window size.

Here's what I have. These width values (first value) accurately match with the width the HTML element must be (second value). However I need to get a formula for this to be able to set the width of the HTML correctly according to any possible window size.

window width / HTML element width

  • 1663 = 1916
  • 1221 = 1692
  • 1119 = 1641
  • 1038 = 1602
  • 630 = 1396

  • 1500 = ????

  • 1400 = ????
  • 2000 = ????

I've been staring at this four hours but I just can't wrap my head around it..

Any help would be appreciated.

Thanks in advance, Roel

    All of your equations are false. $1663$ is _not_ the same as $1916$", and the $=$ sign does _not_ mean "corresponds to, in some unspecified context-dependent way".2012-04-26

Linear regression gives: $m=0.5030755166$ $c=1078.8117490$ with $R^2=0.9999778405$. This gives the desired values as

  • 630 1396
  • 1500 1833
  • 1400 1783
  • 2000 2085

    I'm sorry I'm a complete mathematics noob :P .. What does mx mean? Do i have to multiply m with x before adding it to c? --thanks again2012-04-26
