PowerPoint provides two types of shapes: open and close shapes. In Figure 1 below you can see a thick weighted outline around both a closed shape (on the left) and as an open shape (on the right). Shapes, such as rectangles, circles, etc. are closed shapes. Regular line shapes, such as straight lines, curves, scribbles, etc. are open shapes. Arrowheads can be added only to open shapes, like the one on the right in Figure 1. That's because an arrow needs a pronounced, visible beginning and end.

Figure 2 below shows some samples of lines with arrowheads on one or both sides.

Follow these steps to add or edit arrowheads:
- Open your presentation and select the open shape that you want to format.
- Alternatively, if you want to start from scratch, launch PowerPoint. Most of the time, PowerPoint will open with a new slide in a presentation, you can change the slide layout to Blank by selecting the Home tab | Layout | Blank option. Then, insert an open shape and select it.
- We selected a Line shape, as shown in Figure 3. Selecting the shape brings up the Drawing Tools Format tab in the Ribbon, as shown highlighted in red within Figure 3. Activate this Ribbon tab by clicking on it.

- Within the Drawing Tools Format tab, click the Shape Outline button (highlighted in red within Figure 4). This bring up the Shape Outline drop-down gallery, as shown in Figure 4. From the Shape Outline drop-down gallery, choose Arrows to bring up the Arrows sub-gallery, as shown in Figure 4.

- Within the Arrows sub-gallery, choose any of the available arrow styles. Alternatively, choose the More Arrows option highlighted in blue within Figure 4, above. This summons the Format Shape Task Pane, as shown in Figure 5.

- Within the Figure 5 above all options except those concerned with arrows have been faded out to highlight the un-faded areas referred on this page, your pane will not have those areas faded out. These other options have already been explained in the Formatting Outlines for Shapes tutorials for Weight and Dash Styles.
- You can customize your arrow style by changing the Begin Arrow type, the Begin Arrow size, the End Arrow type, and the End Arrow size.
- Figure 6 shows the Begin Arrow type drop-down, the End Arrow type drop-down has the same options. In both these drop-downs, you'll find options for 5 arrow styles, and a No Arrow option. You can choose any of these 5 styles. We have used Stealth Arrow style as you can see in Figure 6.
Figure 6: Begin Arrow type options
- You also have nine different choices regarding the size of the arrowhead, starting from Arrow L Size 1 to Arrow L Size 9 (letter L stands for left). Figure 7 shows you the Begin size drop-down, and not surprisingly, the End size drop-down offers the same options! But the only difference will be that the letter R, denoting Right will replace the letter L.

- After choosing required arrowhead style and size, you can see the line shape with arrowhead applied, as shown in Figure 8.
