The Nine-Step Chevron That Only Works on One Screen
A 10-slide process overview uses a chevron diagram of nine rounded rectangles with 14–22 word captions set at 18 pt. On the 16:9 meeting room TV everything fits. The same file is also projected on a 4:3 projector in a training room and printed as a handout. After scaling, captions spill out of their shapes, three arrows no longer line up with the chevrons, and step 6 reads before step 5 because the shapes on that row were flipped rather than rotated. Two factory-floor photos look soft when projected and are 6 MB each; a third image is a screenshot containing 8 pt text. An accessibility review flagged missing alt text and the light-grey captions on white.
1. How do you make the diagram survive 16:9, 4:3, and print without rebuilding it three times?
Read the worked answer
Treat the diagram as one object with a defined reading order, then let it scale.
- Group or convert. Group the nine shapes plus connectors into a single group so it moves and scales as a unit; if the layout is genuinely a sequence with labels, rebuilding it as SmartArt (Process > Chevron or Basic Process) gives automatic even spacing and text that resizes with the shapes. The cost is less pixel control; the gain is that it survives future edits.
- Fix the geometry properly, not by eye. Use the Size and Position pane to set identical width and height and a consistent left offset for every chevron, and Align > Distribute Horizontally for the row. That is what the arrows are failing to track.
- Fix the flipped row. A flip mirrors the shape including its text; for a chevron the direction change is intended but the text should not mirror. Rebuild that row by rotating 180° or by using the correct chevron variant, then re-enter the captions.
- Design for the smallest canvas. Place the group so it fits inside a 4:3-safe area on the slide, so the 16:9 version has margin and the 4:3 version has no clipping. Anything outside that box is decoration and gets cut.
Then test: switch the slide size to 4:3 in a copy (Design > Slide Size > Custom) and look at it, and print-preview the handout before declaring it done.
2. The captions still overflow at 18 pt. What do you change, and what do you refuse to change?

Overflow at 18 pt across nine shapes means the text volume is wrong for the layout, not that the font is too big.
Change: cut the captions. Nine chevrons at readable size on a 4:3 projector can carry roughly 6–10 words each. Move the full sentences into the speaker notes so the presenter still has them, and keep a short verb phrase on the shape. Use Format Shape > Text Options and turn off any autofit that shrinks text below about 16 pt - shrinking to fit is how you get a diagram that is unreadable in the back row.
Refuse to change: do not reduce to 12–14 pt to preserve wording, and do not add a second line of text outside the shape boundary - that is what breaks the alignment you just fixed and it looks like an accident on a projector.
If the words truly cannot be cut, the layout is wrong: split nine steps into two rows of four plus one highlighted step, or replace the chevrons with a numbered list. A diagram that needs 20 words per node is a list wearing a costume.
3. Handle the images and the contrast/alt-text findings together, with a print handout in the deliverable.

Photos. Soft projection usually means the image was scaled up beyond its native pixels for the area it occupies. Use Picture Format > Compress Pictures with Apply only to this picture off and target the highest resolution your output needs - print generally wants ~220 ppi at final size, screen ~150 ppi - and crop rather than stretch. Compressing the two 6 MB photos is safe; compressing the small-text screenshot is not, because JPEG artefacts destroy 8 pt text. Better: retake or re-export the screenshot at a larger size, or replace it with real text and shapes so it stays crisp in print.
Contrast. The light-grey on white captions fail at projection distance regardless of the formal ratio. Darken the text or darken the shape fill; do not rely on bold alone. Check the result on the actual projector if you can, since venue gamma is unpredictable.
Alt text. Every photo and the diagram group need alt text (right-click > Edit Alt Text). For the diagram, the alt text should carry the sequence - 'Nine-step process from intake to closure' plus the step names - because a grouped shape diagram is otherwise invisible to a screen reader, and the print handout is the fallback for anyone who cannot see the slide. Mark purely decorative shapes as decorative so they are skipped.
