The font size of my Gmail signature looks weird — it sometimes changes even in mid-sentence, and this is only visible outside Gmail, e.g. in the Inbox app on my iPhone. How to fix?

Under "Settings" on the "General" tab, you should see something like this:
This allows you to define how your default text looks: which font is used*, font size (Small, Normal, Large, Huge), and font color. (There is an additional button to remove existing formatting you may have applied.)
If that doesn't do what you need you may need to increase the font in your browser. (Ctrl+mousewheel is probably the quickest way to do that.)
* currently Sans Serif, Serif, Wide, Narrow, Comic Sans MS, Courier New, Garamond, Georgia, Tahoma, Trebuchet MS, or Verdana
Apparently this problem is known to Google:

Switching signatures doesn't work in plain text
Reported 29, October
It's possible to have unique signatures in Gmail for each sending address associated with your account. Currently, switching signatures when you change the "from" address of a message only works properly in rich text mode. Click Rich formatting at the top of the compose field to change modes.
Based on this, saving the signatures as rich text should help, but I don't have this button. So I have to wait, until Google fixes this.
Update: Google fixed it!
For me, it works again. It seems, that Google has fixed the problem.

Step 1
An optional diagnostic step, just so you can see what's going on. Send yourself a test email and look at it on your iPhone (or through whatever email reader your emails/signatures tend to look weird on). If it does indeed look weird, open it in Gmail on a desktop/laptop; click the menu next to the reply icon, and you'll see a list of options including "Show original". Peer at the HTML code and you should see that some of the tags (like
<div style="...etc.">) break up the writing.Step 2
These instructions are for Chrome. Instructions for other browsers shouldn't be hard to figure out.
To fix, go to the text input where you typically edit your signature and pull up the text of your signature in there. Go to View > Developer > Developer Tools. Hover your mouse over the topleftmost button and confirm it says "Select an element in the page to inspect it." (If this screen is too small, click the toprightmost button, then the icon that says "undock into separate window" when you hover your mouse over it.) Click the "select an element" button, then click on the text input where you enter your signature.
The DeveloperTools window should now become visible, and you should now see some HTML including a line that begins
<div class="gmail_signature">.Step 3
Two methods:
Step 3a
Hard method: Right click (or control-click) on this line, and click "Edit as HTML". You are now editing your signature as HTML. To make the appearance consistent, one thing you could do is to make sure that each
<div>contains a<span style="font-size:12.8px">.Step 3b
Easy method: You should see lines saying
<div>or<div dir="ltr">, and the most-indented lines might begin<span. (Click on the little arrows to show deeper indent levels.) Make sure the most-indented<div>lines just match this pattern:<span style="font-size:12.8px">[some text here]</span>. To fix HTML, right click (or control click) a line and click Edit as HTML, then when you're done click outside that text input that opened up.When you're done, click "save changes" at the bottom of the Gmail settings page. If the "save changes" button is not clickable, go to the signature editor input, add a space to the end, then remove that space. That should make the button clickable again.
Then send yourself a test email, and use step 1 to figure out how to check out whether the HTML is being generated correctly.
Good luck!
