@EasyTrieve there is no such setting in LO v5.3.0.3
@Ratslinger, good that he isn’t using 5.3. Is the fact that this is missing a bug in your opinion? (BTW 5.3 still crashes when I close it which is why I’m not using it yet).
@EasyTrieve Thanks! Yes, that’s better. I’m 62, and those tiny fonts are in fact straining my eyes. Your example looks good because your example only has a few records- in a full screen listing (of 74+ records) the font starts crowding the cell lines, so 150% is about the max that looks good. I don’t know how to post a screen capture in the comments section to show you.
@EasyTrieve It appears there are too many bugs in v5.3 which affect Base (as well as other areas). It’s like re-visiting the release of v5.0 all over. Will go back to v5.2.x today until they can resolve most of these newly created problems.
@EasyTrieve Scaling works fine in v5.2.5.1 - raise it up & bring back to 100% after closing/opening documents.
Part of the problem is using the tiling manager. The base screen becomes proportionate to the tiled area. To increase the items so they are larger you can use the Zoom in the lower right corner (or View->Zoom from the menu) to increase the form items: 
but this will not increase the frame surrounding the form or the icons. It will also mean lots of scrolling around.
Now if you are actually talking about the Font size, that is controlled differently depending upon what you are dealing with. The form background is just like a Writer doc. Whatever is typed directly on the form is controlled thru the Formatting toolbar. Text within controls is set within the control properties. Unfortunately this does not include the Table control. This seems to be buried deep within the control.
@keithostertag First you are doing a couple of things wrong using comments and ID’s. You placed a comment to me under the wrong answer. With the ID you are attaching the - directly to the name and with that it is an invalid ID - SB @Ratslinger - and not @Ratslinger-. Also you need to be more careful on reading what is said in answers & comments. Nothing was ever stated that Zoom did not work for a Table control, just the controlling of the actual font size. It will zoom with rest.
Just to be clear, Zoom and Font size are two DIFFERENT things. Zoom is like looking through a magnifying glass. Font size changes the character size itself an has no effect on the container it is within so a large font in a text box may easily exceed the actual size of the frame.
Thanks for the corrections about the use of this forum user interface.
My tiled table window uses the entire vertical dimension of my screen, one record on each of 74 lines on my screen. That makes the characters pretty small. I want to know how to increase the font size so that, say, maybe 50 records are displayed in the total vertical screen size, making the characters larger and easier to see. I don’t want zooming, and it’s not available anyway (as you show above) in my table view.
Ok. There’s the problem. You are talking about viewing a table not anything to do with a form. I know of no way to change font size when viewing tables. But that is not the real problem. I believe this is because of the tiling. It is squeezing the table size you had before you put it into a panel. You should (don’t use tiling so just imagining here) go full screen with the table view, reduce its’ size by dragging sides or corners then place back in paneled area.
For further clarification, there is no zoom menu option under the View menu tab when looking at a table in my system. That’s what I meant when I said that zoom does not work for a table- it is simply not an available option through the Base menu interface. I was hoping someone would tell me a key combo, menu option or configuration option for increasing the font size when viewing a table.
I checked again on a Windows7 machine, and it is no different from my Linux tiled window system. So the issue is not due to tiling on the tiled window manager.
Maybe the real lesson for me to learn here is… perhaps it is not so common for people to spend time viewing tables. Perhaps most people rely on forms and/or reports, and I should become more comfortable with using them instead of relying on table views. That’s another product of being a beginner and not having a clear picture of what to expect in terms of the power and common use of certain features.
So you are saying the table shows OK on a Windows 7 machine?
Also, can’t you change the resolution in a tiled area? This may be another potential problem.
I see in the the i3 guide you can also change fonts. Again, it appears it is something in the tiling program.
Yea, I could probably change the i3 system font, but that’s not the solution I was asking for. I was asking if there was a way to change the font in Base for viewing the tables. The “problem” isn’t in the tiling window manager, since, evidently, there isn’t such a control in the Windows7 version either- evidently is simply isn’t a feature of the Base program.
What monitor resolution are you using?
I stand somewhat red faced. Didn’t really know what i3 was. Thought was add-on. It a desktop. Installed it on Mint 18 and did many things with tables (although this may be last time I use it). No problems viewing tables. Since you haven’t stated previously, I’m guessing you are running Ubuntu. Reason - tried it (v14.x - 16.4 Unity) and each time I had a problem with tiny font sizes. Made it near impossible to work with base. Once the system font size was changed, all aps worked better.
@Ratslinger Thanks for your help! You are a smart & tenacious guy! BTW- I really love i3wm, I have been using it with Debian (not Ubuntu) for years. Highly configurable, very well supported, and you can configure it to use floating windows if you want (I don’t). It’s geared for people who prefer keyboard over mouse, and who want a lot of control over their desktop. And I like that all the configuration is in a simple text file which is easily edited.
