Windows Paint has a simple grid tool that is accessible through the program's View tab. The tool facilitates image alignment and is useful as a reference to measure the sizes of the shapes that you draw. Although the tool is not as robust as the ones that you will find on more advanced graphic editing programs -- for example, it lacks the "Snap to Grid" feature -- it is still serves its purpose as an alignment tool.
Press the "Windows" key, then type "Paint."
Select "Paint" from the Results screen to open the Paint program.
Open the "File" menu, then select "Open." Browse to the image that you want to view, then double-click the image file to open it in Paint. Alternatively, if you want to create a new blank file, open the "File" menu, and then select "New."
Click the "View" tab on the Paint ribbon.
Select the "Gridlines" check box in the Show or Hide group. A grid will appear overlaying the Paint canvas area.
To maintain the aspect ratio of a preset shape, click the shape you want to use from the "Shapes" group, and then hold down the "Shift" key as you drag the mouse.
You can also activate the Rulers tool as a further aid. Click the "View" tab, then select the "Rulers" check box in the Show or Hide group.
If you want to set the size of the picture, open the "File" menu, and then select "Properties." Use the available settings to set the images size.
Click "Zoom in" to get a closer view of the canvas. The grid lines will appear more widely spaced apart.
Click the 'Home" tab to access the Paint drawing and painting tools. Click a tool to begin drawing.
