My Gmail mail window getting very wide, off the screen wide. A person replied with an answer and said to ctrl + roll down and then reset.

But can someone please explain what "roll down" means? I have not "roll down" key on my computer and don't see any explanation when I google it. I am having this wide screen problem in Google Chrome ...

I have the bar at the bottom but I would really like a way to resize the gmail text window ... when I resize the chrome window, it just hides the text in my gmail message that I am typing.

  • Simple workaround to this 6 year old problem: Go to Reply to (<-- V) menu above edit box. Select "Change Subject" from the menu. This puts you into the pop-up editor and margins work! Sorry, they won't let me "answer" this problem...

Change the Display Mode (gear in the upper right) to Touch-enabled then change it back to your preferred Display mode.

    that solution does not work for me, window is still too wide, seems to be some emails forcing the window to be wide Jan 10 '18 at 14:21

The action you're referring to is Ctrl + scrolling down on your mouse's scroll wheel. This will zoom out and hopefully make your content fit.

A similar method of the same action would be Ctrl + -.


Without a mouse to "roll" down to change display size, you can press and hold Ctrl while you press the keys with "+" or "-" (plus or minus signs) to increase or decrease size.
