Although Excel is mainly used for numbers and formulas, it also features a drawing tool that enables us to insert pictures, lines and shapes.  This article provides a step-by-step tutorial on how to draw lines.

How to draw a line?

In order to draw a line, we make use of the drawing tool:    

  • Click Insert tab > Shapes Lines

From the drop-down menu, we choose the type of line we want to insert.  The choices in the menu are: Lines, Arrows, Curves, Free-form and Scribble.

  • Select the first line button
  • The mouse pointer will then show a plus “+” sign.  We click the mouse button anywhere on our worksheet where we want to place our line, then hold and drag it until the desired length and orientation is achieved
  • Release the mouse button

We have now successfully created a line through the drawing tool.  The image below shows a diagonal line.

Draw a perfectly straight line

If we want to draw a perfectly straight line, we have to drag the line to the right and keep a straight line as we move the cursor across the screen.  There are times, however, when we still end up with a slightly slanted line even when we have diligently tried to make the line straight.

Below image is an example of a slanted line with a height of 0.05 cm.

A perfectly straight line must have zero height.  Hence, we can make any horizontal line straight by changing the height to zero “0 cm”.

Tip:  

While drawing a line, we can make it straight by pressing the Shift key on the keyboard while we drag the cursor to attain the desired length.

Customize a line

After we draw a line, we can customize it through any of the following:

  • Right-click the line and choose from the menu.  We can change the connector type or format the line color, style, size, position, etc.

  • The connector types to choose from are Straight, elbow or Curved

  • We can choose from the built-in pre-set styles or format the line color, weight and dash style.

  • For more formatting options, we can select Format Shape after we right-click the line to launch the Format Shape dialog box.

Format Shapes offers all the formatting options that we need when we draw a line such as line color, weight and types, shadow or glow effects, 3D rotation, size and properties.
