How to make your screen share readable for everyone watching
Text on a shared screen arrives smaller and softer than it leaves. Six fixes you can make before your next session, and what each one costs you.

You share your screen, start talking, and a minute later somebody asks if you can make it bigger. So you do. Now your editor shows twenty lines instead of sixty, the panel you needed is off the edge, and you spend the rest of the session working in a setup that isn't yours.
It is one of the most common complaints about presenting a screen, and people describe it the same way wherever they talk about it. One developer on Hacker News put it plainly:
"people want my font sizes to be 3x what I have them"
It isn't only a remote problem. In a study of live-coding classes, an instructor described a lecture room with four large displays and still:
"if you don't have eagle eyes, you can't see them. It's still too small."

Why a shared screen is harder to read than your own
Your screen is drawn into a window on theirs, and that window is almost always smaller. A wide monitor shown in half of a laptop screen shrinks everything on it by the same amount, and small text shrinks past the point where letters can be told apart.
Then the picture is compressed to travel. Compression is kind to large flat areas and hard on fine detail, and the finest detail on most screens is text: thin strokes, small punctuation, the difference between l, 1 and I. That is why a shared slide with big headings reads fine and a spreadsheet or a terminal does not.
Both problems get worse together. The larger your screen, the more it is shrunk, and the more detail compression has to throw away.
Six fixes before you share
1. Share one window, not the whole screen
A single window is smaller than your whole screen, so it is shrunk less on the way to theirs. It also keeps notifications, other tabs and your desktop out of the picture. If you need to move between two programs, put them side by side in one window-sized area rather than sharing everything.
2. Present at a lower resolution, or a higher scale
On Windows, Settings → System → Display → Scale makes everything on your screen larger without changing what you are showing. Moving from 100% to 150% for the length of a session does more for the people watching than any font setting, because it enlarges the menus and labels as well as the text you remembered to change.
3. Turn up the text in the program you are showing
Most tools have a presentation size. Code editors have a zoom command, spreadsheets have a zoom slider, and every browser enlarges a page with Ctrl and +. Set it before you start, not when somebody asks, so you aren't rearranging your work in front of everyone.
4. Choose contrast over looks
Dark text on a light background, or light on dark, with nothing in between. Thin, light-grey fonts and subtle syntax colours look good on your monitor and disappear after compression. If your tool has a high-contrast theme, a session is the time to use it.
5. Hide what you aren't talking about
Side panels, toolbars, the file tree, the minimap. Every one of them takes room from the thing you want read. Close them, and the part you are explaining gets larger without anything else changing.
6. Magnify the part you are on
Windows has a magnifier built in: Windows key and + turns it on and zooms in around your pointer, and Windows key and Esc turns it off. It is the quickest way to show one cell, one line or one setting at a size everyone can read, then go back to your whole screen.
What these fixes cost you
Every fix above changes your screen for the room. They work, and most of them are worth doing. But they all move the work onto you, and they all trade away the thing you are trying to show: a real setup, at the size you use it.
People who present often notice this cost first:
"The issue is when I have to share code, because my font is huge in my editor."
The other answer, asking people to zoom in on their side, has its own problem. Most of the time it doesn't work, because the picture that arrived is already the small, softened one, and enlarging it only enlarges the blur. And it lands badly:
"Telling viewers to zoom in if they can't read anything sounds like you're blaming them for the problem."
Letting each person zoom in themselves
The fixes trade your setup for their readability because, in most screen sharing, everyone receives the same small picture. If your whole screen arrives at the size it is on yours, each person watching can zoom into the part they need, as close as they need, and the words stay sharp, because the detail was there all along.
That is how Quisnap works. You share your screen as you normally have it. The people watching open a link in their browser and zoom in with the scroll wheel, around wherever they point, and nothing moves on your screen. If they need the words themselves, they can select and copy them straight off your screen.

In short
- Share one window rather than the whole screen.
- Raise your display scale for the session.
- Set the text size in your tool before you start.
- Prefer strong contrast to a pretty theme.
- Close the panels you aren't talking about.
- Magnify the one part you are explaining.
- Or share at full size and let each person zoom in for themselves.
