Is it possible to change text size after it has been placed in AutoCAD?

ByCADbrief Staff

Short Answer

Yes — you can change text size after it has been placed in AutoCAD by selecting the text and editing its Height in the Properties palette, which is the most common professional method. For Mtext, single-line text, and dimensions, PROPERTIES is usually the fastest tool. A limitation is that annotative text may scale differently across viewports.

What You Need to Know Before

Warning: If the text uses a text style with a fixed height, you may not be able to change the object’s height directly in Properties. Also, locked layers or annotative scaling can make it look like the text size did not actually change.

How to Change Text Size After Placement in AutoCAD

  • Command: PROPERTIES

  • Shortcut: Ctrl+1

  • Quick Steps:

    1. Select the text object, then open the Properties palette from the Ribbon Home tab > Properties panel, or press Ctrl+1.
    2. In the Properties palette, find the Text section and change the Height value.
    3. Press Enter and confirm the result; if the text is annotative, also check the Annotative property and assigned scales.

Variables & Settings

  • Key Setting: Text Style height

  • Expert Setting: If the assigned text style has a nonzero fixed height, AutoCAD controls the text size through the style, not the individual object. Set the style height to 0 in the Text Style dialog if you need per-object height control.

Why it Fails

  • Cause 1 (Geometry): The text is annotative, so its display size is controlled by annotation scales rather than only by the raw height value.
  • Cause 2 (Layers/Locks): The text is on a locked layer, so the height property cannot be edited.
  • Cause 3 (Command/Logic): The text style has a fixed height, which prevents direct object-level size changes in Properties.

Quick Fix & Best Practice

  • Quick Fix: Use STYLE and set the text style height to 0, then reselect the text and change its Height in PROPERTIES.
  • Manager’s Verdict: Use Properties for fast one-off edits and small batches. For office standards, control text size through text styles and annotative settings to keep drawings consistent.

FAQ

Can I change the size of multiple text objects at once?
Yes, select all target text objects and change Height once in the Properties palette.

Why is the Height field grayed out in AutoCAD?
Usually the text style has a fixed height or the object is on a locked layer.

Can I change Mtext and single-line text size the same way?
Yes, both are commonly edited through the Properties palette, though available options may vary slightly.
