Putty is a free and open source terminal emulator and probably the best client for SSH in Windows. The one little irritating problem I face while using Putty is the number of lines in the window. The default windows size of Putty is 200 lines. Which means, you cannot see just 200 lines by scrolling back. And these 200 lines are not at all sufficient for programs that have huge logs.

More often than not, I need to see more than 200 lines back in the logs while working. For this purpose, I change the window scrollback size to 20,000 or 50,000. But if you do this, you have to do it every time you use Putty which is not very convenient. Would it not be great if you could permanently change the window scrollback size of Putty so that you won’t have to change it every time?

In this quick tip, I’ll show you how to permanently change the window scroll size of Putty.

Permanently change Putty window scroll size:

I don’t need to tell you that you must have Putty installed beforehand. Follow the steps below to change Putty window size:

• Open Putty. No need to log in to any session.
• From the left sidebar, choose Window. In the right pane, see the option of Lines of scrollback. Change it to a value of your choice.
  
• Now, the number of lines in Putty have been increased to 20,000. The next step is to make this change permanent. Choose Session from the left sidebar. Now, from the right pane, click on Default Settings and click on Save.
  

That’s it. The next time you use Putty, the window scroll size will we what you had entered. So you can easily see the large logs. Hope it helps you. Questions, suggestions? Feel free to drop a comment below.
