How to Add a Text Box Constraint in Blender

Constraining a text box in Blender allows you to control paragraph wrapping, prevent text from extending infinitely on a single line, and keep your typography neatly contained within a defined geometric area. By configuring the Text Box settings inside the Object Data Properties panel, you can set precise width, height, and offset parameters that force text to automatically wrap and conform to your layout boundaries.

Step-by-Step Guide to Adding a Text Box Constraint

1. Select the Text Object

Select your text object in the 3D Viewport. If you have not created one yet, press Shift + A, hover over Text, and left-click to insert a new text object.

2. Open Object Data Properties

In the Properties Editor (usually located on the right side of the workspace), click on the green Object Data Properties tab, represented by a capital letter "F" icon.

3. Navigate to the Paragraph Section

Scroll down to the Paragraph foldout menu and expand it. Inside this section, locate the Text Boxes subsection.

4. Define the Text Box Limits

By default, the width setting is set to 0.000, which allows text to grow horizontally without wrapping. To constrain it:

  • Width: Change this value above 0.000 to set the maximum width of the frame. Once text reaches this boundary, it automatically wraps to the next line.
  • Height: Enter a value to cap the vertical limit of your text area.
  • X Offset and Y Offset: Adjust these parameters to shift the starting position of the text box relative to the object's origin point.

5. Add Multiple Text Boxes (Optional)

If you are creating complex layouts like columned text:

  • Click the Add Text Box button inside the Text Boxes panel.
  • Set the width, height, and offsets for the new box. Blender will automatically flow overflow text from the first box into the next defined box.

Once configured, any text typed in Edit Mode (Tab) will respect these spatial constraints seamlessly.
