Here’s a general guideline for monitor screen distance:

• Get the screen as far away from you as you can and still be able to read it clearly with good posture.

• This will be about arm's length plus a couple of inches.

Monitor distance modification

• Bringing your monitor closer is generally as simple as sliding the screen towards your body.

• Moving it farther is generally a bit more complicated if simply sliding it farther away isn’t an option.

• First, figure out why you can’t get your monitor farther away.  It may be that you can reorganize what’s on your worksurface and get the monitor farther away.

• If it’s not possible to reorganize your worksurface, consider reconfiguring how you place your monitor on the desk.  For example you might be able to place the monitor more in a corner of the worksurface to gain greater distance.

• Another option you may have is to add a keyboard tray to the existing worksurface.

• At a minimum, when you’re not doing a great deal of keyboard data entry but are primarily reviewing documents on your monitor, simply push your chair farther back from your worksurface to give your eyes a bit of a break
