# Product dimensions diagram survey

Improve dimension diagrams.

If nothing was unclear or difficult, say so. Skip questions about steps you did not experience; use not applicable where appropriate.

## 1. Which measurement were you seeking?

Answer: ____________________

## 2. What diagram label was ambiguous?

Answer: ____________________

## 3. What unit information was missing?

Answer: ____________________

## Author notes / illustrative keys where applicable

1. Identify whether the shopper needs body width, overall width, depth, clearance or another measurement for their intended placement. An overall satisfaction answer cannot tell the diagram owner which boundary is missing.
2. Ask which arrow endpoints or labelled surfaces the reader interprets differently. Distinguish the product body from handles, hinges or packaging so a drawing repair addresses the actual ambiguity.
3. Find whether units, rounding or a conversion explanation are absent. Any numbers added to the diagram must come from verified product specifications, not respondent estimates.

Interpretation caution: Use manufacturer-verified dimensions.


## Distinguish the diagram’s measurement boundary

Use a verified fictional dimension diagram; these examples make no fit promise.

### External product width

Keep separate: Internal usable width or packaging width.

Why the boundary matters: Readers need to know which physical boundary the arrow measures.

### Stated measurement unit and orientation

Keep separate: An inferred clearance or compatibility guarantee.

Why the boundary matters: Verify the actual space and product conditions separately.

## Illustrative finding and follow-up

Observation: Diagrams omit whether dimensions include handles.

Action to test: Define the measured boundaries.

Follow-up: Ask readers to locate the body width and overall width on the revised diagram and explain whether handles are included. Record mismatched boundary interpretations; check the drawing separately against manufacturer-verified measurements.


## Collection protocol

When and whom to ask: Show adult shoppers the actual dimension diagram or a labelled synthetic example before they decide whether an item fits. Ask about interpretation without requesting an address or private room photograph.

Decision owner: The product-information owner with the person responsible for verified measurement drawings.

Follow-up: Ask readers to locate the body width and overall width on the revised diagram and explain whether handles are included. Record mismatched boundary interpretations; check the drawing separately against manufacturer-verified measurements.

Response handling: Collect the measurement needed and the label interpretation. Avoid private installation details and keep synthetic dimensions clearly labelled.
