Dear @CB23,
I hope you’re having a good day
Based on the behavior you've described, I do not believe this is a bug. After testing similar scenarios in PowerPoint, including with PowerPoint's built-in Title and Subtitle placeholders, I observed that text can appear to start at slightly different visual positions even when:
- Both text boxes are left-aligned.
- The left margin is set to 0 cm.
- The left edges of the text boxes are perfectly aligned.
My understanding is that PowerPoint aligns text according to its internal text layout and font rendering rules rather than the leftmost visible pixel of the first character. Because of this, a 0 cm left margin does not necessarily mean that the visible edge of the first letter will sit exactly on the text box boundary.
In other words, the left margin setting controls the text container, not the visible outline of the glyph itself. The small offset you are seeing appears to be a result of how PowerPoint positions and renders text within the text box rather than additional padding being applied.
I agree that the behavior can be surprising, especially when trying to achieve pixel-perfect alignment, because visually it does look as though a left margin still exists. However, from my testing, the observed behavior appears to be consistent with how PowerPoint's text rendering engine works rather than an indication of a defect.
If precise visual alignment is required, the practical approach is usually to align based on guides or the visible text itself rather than relying on the text box boundary alone.
I hope this information helps point you in the right direction.
Warm regards,
