Solution 1Recommended

Use Field Alignment and Sizing Tools

Use Acrobat's native properties menu to instantly match the width and height of multiple form fields and align them perfectly.

Acrobat Pro DC includes built-in form field tools that allow you to match the exact dimensions of a master checkbox to all other selected checkboxes, eliminating the need to resize them manually.

1
Select Multiple Checkboxes

In 'Prepare Form' mode, hold down the Ctrl (Windows) or Command (Mac) key and click to select all the checkboxes you want to modify.

2
Set Fields to Same Size

Right-click the specific checkbox that has the correct dimensions you want the others to match. From the context menu, select 'Set Fields to Same Size' and then click 'Both' to match width and height.

3
Align the Checkboxes

With the checkboxes still selected, right-click the master checkbox again, choose 'Align, Distribute or Center,' and select your preferred alignment (e.g., 'Align Left').

Use Field Alignment and Sizing Tools
Pro Tip: You can also use the 'Distribute' option in the same right-click menu to ensure equal vertical or horizontal spacing between your checkboxes.

Frequently Asked Questions

Why do my checkboxes resize automatically when I move them in Acrobat?

This typically occurs if you accidentally click and drag the resizing handles (the small dots on the corners of the field) instead of clicking the center of the field to move it. Always grab the center of the field to drag and drop without resizing.

Can I align checkboxes horizontally and vertically at the same time?

You can set checkboxes to the exact same size simultaneously, but alignment usually must be done in two steps: first aligning the edges (e.g., Align Left), then distributing them evenly along the axis (e.g., Distribute Vertically).

How do I change the default size of a new checkbox?

After formatting a checkbox to your preferred size and style, right-click it and select 'Use Current Properties as New Defaults.' Any new checkboxes you draw will now automatically share these dimensions and settings.
