How can I write normal-sized fraction?

Ugly equation:
Left side: one usage of equation builder. Increase font size.
Right side: use another instance of equation builder.

In this example, 30px on the left, 18px on the right. The formula writer tried to keep the box (container for formula) the same height as the rest of the line height; shrink to fit.

  • Thank you. It seems it not always work changing font for an existing equation. Jun 10, 2016 at 11:05

    If you make two equations it should work out visually for you. It really is one equation, but it's in two parts. The equation becomes an Object when you use the equation builder. The Object is shrunk down to fit the height of the Line and that's why the equation gets really small. So use two parts if only one side is a fraction.

Select the whole equation box, and change font size normally

    Doesn't this change the font size for the entire equation? That's probably not what the OP wants. Oct 2, 2017 at 14:31
  • No really it does Oct 3, 2017 at 14:41
  • You have to change the font size for the whole line that the equation is in. If you have text other than the equation in the same line, and try to only increase the font size for the equation, it won't work

  • Worked for me. The font of the whole equation is changed, but it looks that, now the font in the fraction matches the rest of the text.

To change the size of the equation font you have to change the font size of the whole line that the equation is in


Selecting the "whole equation"

I found this difficult to get right at first, so I am expanding on the accepted answer of @Omar Elrefaei.

At first I thought I was selecting the "whole equation" with the above selection, but changing the font size had no effect.

Then I realised I needed to expand the selection a tiny bit more. In my case, by pressing SHIFT Right arrow.

The highlighted area expanded very slightly (in my case, downwards) giving this appearance. enter image description here

Now, adjusting the font size on the menu does indeed increase the font size of the equation.
