What is the easiest way to get one and a half line spacing in all my tables? I have the setspace package loaded, if that helps. The relevant bits of my preamble currently read:


This gives me one half spacing for my body text and the captions of figures/tables/etc.

  • \extrarowheight? Of course, would be easier with an MWE. – cfr Nov 24 '15 at 3:50
  • As far as I can tell, \extrarowheight adds a fixed amount of space, so is not a general solution that works for all text sizes. – Ulysses Nov 24 '15 at 5:30
  • Something similar is \renewcommand{\arraystretch}{X} where X is some number. 1 appears to be the default which reproduces single spacing. I don't know what X needs to be to reproduce one half spacing, only that 1.5 isn't it (too big). – Ulysses Nov 24 '15 at 5:37
  • According to setspace, it is ~1.25, depending on the font size. – Bernard Nov 24 '15 at 11:34

The answer depends a bit on what "onehalfspacing" entails. If it's equivalent to \setstretch{1.5}, you should try \renewcommand\arraystretch{1.5}.

If your tabular-like envrionments are located inside table environments, and if you're using the terminology of the setspace package and your main font size is 10pt, you should try \renewcommand\arraystretch{1.25}; for 11pt and 12pt main font sizes, you should use values of 1.213 and 1.241, respectively.

In the screenshot below, the left-hand and right-hand tabular environments are typeset before and after a \renewcommand\arraystretch{1.5} is executed, respectively. (The default value is 1.)

enter image description here

%define a dummy table
   a & b & c\\
   d & e & f \\
   h & i & k \\


  • Thank you for your help. Could you clarify how you got the numbers 1.25, 1.213, etc? – Ulysses Nov 24 '15 at 6:34

    @Ulysses - I found these numbers inside the file setspace.sty, in the section that defines \onehalfspacing. – Mico Nov 24 '15 at 6:49
