Here’s a tip on how to quickly fix a crooked or less than perfectly straight line in PowerPoint. Sometimes you might notice that even though you were holding shift your line still ended up slightly crooked. This kind of an imperfection can drive a designer mad =)
Maybe it’s close to two objects and it’s snapping to a point or grid… well instead of changing your whole page set up just to fix this line here is a quick tip to straighten it out.
When you click the line go to the Format Tab in the ribbon and look at the Size option. On the right you can see that the line above has a height of .05″. Well that’s not the stroke (thickness) of the line. This number actually denotes the height difference in the location of the starting point and ending point of the line. Which means that the end point is raised above the starting point by .05″. (Think of a right triangle. The width of the line is the hypotenuse and the height is the opposite side.) Now all you have to do is just zero that field out and you’ve got yourself a perfectly straight line.
Note in vertical lines you’ll see the opposite effect. The “crooked” difference between the points will be in the width field.
