When I use infinity symbol as a limit of sums, the symbol appears to be very small. I use the following code?

"sum to infinity 2^{-n}"

Can I add something into the code to make the limit symbol bigger? Is there any way to do it?

Thanks.

Yes you can: sum to size*2infinity 2^{-n}

Please add [Solved] at the beginning of the title in your first post (top of the topic) with the 🖉 button if your issue has been fixed.

But it doesn't work for me.

Code: "sum to infinity 2^{-n} newline
sum to size*2infinity 2^{-n}"

What @Hagar Delest posted works for me, but you should probably not tamper with the sizes of single symbols being expected to fit into a scheme of sizes and positions depending on their usage.

The lower limit (strangely missing in your example) and the upper limit of a sum get their sizes based on the respective setting under >Format > Font Size.... We should thoroughly consider these sizes, in specific the relative ones, according to standards, and then apply them to all our formulas. === Editing ===
Sorry. I had made the example with LibreOffice V 7.5.3.2 assuming there wasn't much development in Math for a long time. Now I also tested with AOO V 4.1.7 and found that the limits were formatted with inconsistent sizes. There seems to be a bug.

sum to size*2infinity 2^{-n}"

Missed space between the "size*2" and the "infinity"...

In LibreOffice, with and without the space works.

Not work in my AOO 4.1.13 portable version. It requests a space.

I stand by my advice above.
(The tiny infinity symbol originally complained about may be caused by an improper setting of the relative size for "limit elements". Default seems to be 60% of the base size.)

But IF there is an important reason to use the explicit relative size definition with size*, a factor of 2 will almost always exaggerate, and interfere with the alignment against other elements.
Therefore the hints:
This control statement is relative to the otherwise chosen size of the respective element type, which is also expected to be relative to the base size (default: 12 pt).
The factor need not be an integer! size*1.2, for example, increases the otherwise applied size by 20%.

An example for further testing:
And: Control statements must not contain spaces. Otherwise spaces are welcome.

There is a concept in this thread but it is out of context. May I ask "out of context" questions in threads? This makes the thread unnecessarily longer than it should be. Or should I open a new thread, giving reference the related thread?

Threads often stray from exact compliance with a query, but such additional advice is often quite relevant and offered by experienced Open-/Libre-Office users, in the hope that it will be helpful.

You made me curious. Try a try, and let's see.

By the way: The infinity symbol you inserted into the original subject isn't from the OpenSymbol font, but seems to be from the default font used here. For me the OpenSymbol infinity is clearly larger at the same font size (and not quite symmetric).
