Hello there! I noticed that if I use for example: \usepackage{setspace} \spacing{1.5} I get 55 pages for my thesis, but if I use: \usepackage[onehalfspacing]{setspace} I get 50 pages. I literally want a space of 1.5 pt and I don't understand which one is the true 1.5pt. From where does this strange phenomenon come from? Thank you for your quick tutorial!!
Interesting! I've done a bit of reading and it is actually more complicated than the basic "number of lines" definition which I naively gave in the video... It seems that the scaling factors used in the video are a ratio of the baselineskip (which measures the length from the bottom of one line to the bottom of the next line) compared to the font size. If you change the font size, the baselineskip also changes to accommodate this, so that the ratio will always be around 1.2: 10pt font: baselineskip=12pt 11pt font: baselineskip=13.6pt 12pt font: baselineskip=14.5pt So you are actually redefining this scaling ratio which varies slightly depending on your font size e.g., 10pt font: \spacing{1.25}=\onehalfspacing 11pt font: \spacing{1.213}=\onehalfspacing 12pt font: \spacing{1.241}=\onehalfspacing If you wanted "true" 1.5 scaling, you should probably change the baselineskip in your preamble to be the same as your font size by doing something like "\fontsize{}{}" to make it easy. HOWEVER, I would not worry too much about this. Just stick with \onehalfspacing and this should be good enough for most purposes. Source: tex.stackexchange.com/a/30114
