Changing the Size of a Report

This article covers how to change the size, fit, and aspect ratio of your OnePager chart. There are three main ways to do this:

  • Zooming: If you are generally ok with the proportions of your chart, but just need it to be bigger (or smaller) on the screen, zooming is the best option.
  • Fitting: If you need your chart to fill up the entire screen while you are editing, you can fit the chart horizontally or vertically to fill your display.
  • Resizing: If your OnePager chart looks ok on the screen, but is too wide, narrow, tall, or short when you export or print it, you probably need to change your aspect (width:height) ratio. This will adjust the overall size of your chart, but won't scale fonts or tasks/milestones by the same amount, so is not the same as zooming or fitting.


To change how big or small your chart appears on your display without actually changing the dimensions of your chart, you can zoom in or out. Go to the View tab and click the Zoom In or Zoom Out buttons:

Notice that when you zoom in or out, not only does the chart itself change size on the screen, but all of your tasks and fonts change at the same rate:


To fit your chart to your display, go to the View tab and click on the Fit dropdown:

Here is a chart that has been fit vertically:

Resizing changes the overall dimensions of your chart, and can be used to create (or reduce) the amount of whitespace in the body of the chart. Resizing is not the same as zooming: When you resize, you are changing the size of the chart body, but are leaving other elements like fonts, tasks, and milestones unchanged. So if you want to change the size of your chart, while changing the size of your fonts and tasks/milestones are the same time, you are better off zooming.

Change Dimensions

Go to Home > Chart Properties > Page Layout.

Adjust the Document width and Document height settings at the top of the form. You can also change the standard height of every row to be larger or smaller, which will also change your document height. For U.S. customers, these numbers are measured by default in inches. Most other parts of the world will use centimeters. When possible, we recommend your width be approximately 62% larger than your height; read our blog post on why.

If you need to achieve a specific aspect ratio such as 4:3 or 16:9 for use with PowerPoint, you can ensure that your dimensions are proportional with those ratios. To be clear, your document does not literally need to be 4" x 3" or 16" x 9"; rather, the dimensions need to be in those proportions. For example, 8" x 6" and 12" x 9" are both a 4:3 aspect ratio, while 24" x 13.5" and 32" x 18" are both a 16:9 aspect ratio.

If you are planning to save your OnePager chart to PowerPoint (*.pptx) format, you can change OnePager's PowerPoint aspect ratio from 4x3 to 16x9 to match your other slides.

Changing the dimensions of your chart. This is useful if you need 16x9 aspect ratio or 4x3 aspect ratios.

Click OK to see the new dimensions.

Drag to Resize

First, zoom out so there is blank gray space surrounding your chart. To zoom out, go to the View tab and click the Zoom Out button.

Second, drag the edges of your chart up, down, left, right, or diagonally to resize the chart, just like you would a box or image in PowerPoint:

Drag to resize

IMPORTANT: Notice that when you stretch the chart dimensions, the tasks, milestones, and fonts are not resized. This is because you are changing the size of the canvas, and are not changing the size of the objects themselves.
