Multiple Choice Grid in Google Forms on iPhone (2026)
Which Grid, and When
| You are asking… | Type | Example |
|---|---|---|
| Rate each item on one scale | Multiple choice grid | Satisfaction with venue / food / speakers |
| Pick several per item | Checkbox grid | Which days each volunteer can work |
| Rank items uniquely | Multiple choice grid + limit one per column | Rank 5 features, 1st–5th |
Building one from iPhone is the same flow as any question: add a question, change its type to the grid you need, then type rows (the items) and columns (the choices). Both grid types support the full option set in mobile Safari.
The Two Settings That Change Everything
Look at the grid question controls; Limit to one response per column is in the ⋮ menu, while the required-row control may appear directly on the question:
- Require a response in each row — blocks submission until every row is answered. Review the required-question settings and decide whether every row is relevant to everyone. Add a suitable not-applicable choice where necessary.
- Limit to one response per column — each column becomes single-use across rows, converting the grid into a ranking or unique-assignment matrix. For a full ranking, use a multiple choice grid, require every row, and keep row and column counts equal. Test duplicate selections and the validation message.
Check the Grid on a Real Phone
Small-screen presentation depends on the browser, screen width, and question labels. A wide matrix may require horizontal movement or display differently from the desktop view. Do not assume a fixed stacked layout. Practical checks:
- Keep grids compact: a few rows and 3–5 short columns are a useful starting point, not a universal limit.
- Split big matrices into two grids across sections, or replace them with individual linear-scale questions — they can serve the same research purpose, but labels and response-sheet columns may change. Compare the result before replacing the question.
- Test on your actual phone before sending. Check the published responder link with an intended respondent’s account as well as the editor preview; access rules and layout both matter.
In the response sheet, each row lands as its own spreadsheet column (“Question [Row]”) — short row labels now save you column-renaming during Excel export later.
Grid editing is also the single fiddliest question type in mobile Safari — long row/column lists in a cramped card. It all works, but if matrices are a regular part of your forms, the same editing in our Forms for Google Drive iOS app happens in a native interface built for a phone screen in the first place.
Review grid questions and hand off the answers
On iPhone and iPad. Use Forms for Google Drive for mobile form editing and response review. Test the actual grid on a respondent’s phone after editing; row labels and answer choices should remain understandable on a small screen.
With the Workspace add-on. Form to Docs by pipiform can help turn the form or its responses into a document for a review meeting. Export a small grid example first and check that row labels stay associated with their answers before using a larger dataset.

Frequently Asked Questions
What is the difference between a multiple choice grid and a checkbox grid?
One answer per row versus many. In a multiple choice grid, each row accepts exactly one column choice — the classic rate-each-item matrix. In a checkbox grid, each row can take several columns — pick all days you are available, for example. Choose by asking: per row, is the answer one thing or possibly several?
How does a grid look for respondents on a phone?
The layout depends on screen size, browser, and labels. A wide grid may need horizontal scrolling or appear differently from the desktop view. Keep labels short and test the published responder link on a real phone rather than assuming rows always become stacked questions.
Can I force respondents to answer every row?
Yes. Enable Require a response in each row in the grid question controls. The form will require an answer for every row before submission. Only require rows that apply to everyone, or provide an appropriate not-applicable choice. Control placement can vary with the editor layout.
What does 'Limit to one response per column' do?
It validates that the same column is not used across multiple rows. For a full ranking, use a multiple choice grid, require every row, and use equal numbers of rows and columns. Test duplicate choices and the error message rather than assuming unavailable choices are always disabled.
How do grid answers appear in the response sheet?
Each row becomes its own column in the linked spreadsheet, labeled 'Question [Row]' — a 5-row grid produces five spreadsheet columns. Nothing is lost, but plan column naming: short row labels keep the sheet readable, and exports to Excel inherit whatever you wrote.
Is there a better mobile alternative to a big grid?
Sometimes. Split a large grid into smaller sections or use separate scale questions when the matrix format is not essential. These alternatives can ask about the same topics, but may change labels, exported column names, and the amount of scrolling. Test the new version with a small sample before switching.
