Changing measurements in CorelDRAW, such as the units displayed on the rulers, is a simple process that helps you work accurately for your specific project needs, whether it's for print, web, or other applications.
The primary method for changing your document's measurement units, particularly those shown on the rulers, involves accessing the **Options dialog box**.
## Steps to Change Ruler Units:
Based on the provided reference, here is the exact process:
1. Locate either the horizontal or vertical ruler within your CorelDRAW drawing window.
2. **Double-click a ruler.**
3. The **Options dialog box appears**, with the **Rulers page displayed**.
4. In the **Units area**, which is typically located on the right side of the dialog box, you will find the **Horizontal list box**.
5. **Choose the unit of measure you want from the Horizontal list box**. Select from options like Inches, Millimeters, Pixels, Centimeters, Points, Picas, etc.
**Important Note:** The reference highlights that **when the Same units for Horizontal and Vertical ruler check box is enabled** (which is often the default setting), the units of measure for the vertical ruler are automatically adjusted to match the horizontal ruler you've selected. If you require different units for each ruler, you would need to uncheck this option.
## Common Measurement Units
Here are some common units you might choose from, depending on your project type:
| Unit | Common Abbreviation | Best Used For |
| :---------- | :------------------ | :-------------------------------- |
| Inches | in, " | Print design (US standard) |
| Millimeters | mm | Print design (International) |
| Centimeters | cm | Print design |
| Pixels | px | Web graphics, Digital design |
| Points | pt | Typography, Small measurements |
| Picas | pc | Typography, Layout grid systems |
## Where Changing Units Applies
Changing the ruler units typically affects:
* The units displayed on the horizontal and vertical rulers.
* The default units used when you select an object and view or edit its size and position in the Property Bar at the top of the window.
* Units in various dialog boxes that deal with dimensions and positioning.
Selecting the appropriate unit of measure ensures accuracy and consistency throughout your design process.
