20-Question Bubble Answer Sheet (A–D, US Letter)
Built for the weekly quiz: twenty rows in a single column, A to D on every row, bubbles 5.3 mm across and 6.4 mm between rows. Print it on US Letter at actual size and one page carries the whole test, with the student's name and date at the top. No account is needed.

Twenty questions is the workhorse length for a short class quiz, an exit ticket, a spelling test or a quick homework check. This version puts one question per line down a single column with four bubbles (A–D) on each row, and a header block carrying Name, Date, Class/Period and Test/Form lines so a finished stack can be sorted back to its owners.
Because only twenty rows share the page, the bubbles print at the largest size used anywhere on this site (the specs table shows the exact width). That makes this the sheet to reach for with younger students, with anyone still learning to fill a bubble completely, or on days when you plan to grade by eye instead of with a camera.
Who this sheet is for
- Daily quizzes, exit tickets and bell-ringers
- Elementary and middle-school classrooms
- Hand-grading and grading by eye
- Students who need large, easy-to-fill bubbles
When to choose this sheet, and when not to
Pick this sheet when twenty rows are the whole assessment: a weekly vocabulary check, a spelling test, a reading-comprehension exit ticket. Everything sits on one side of one page, there is no second column to explain, and students read straight down.
If you regularly write tests of thirty items or more, a longer sheet will serve you better, because a twenty-row grid leaves much of the page empty. If responses should be anonymous, use the version without a header block; if you want a bubbled Student ID, use one of the sheets that include the ID grid.
Rows are 6.4 mm apart and bubbles are 5.3 mm wide, which is the largest size this site uses. That makes it a sensible first sheet for students who are still learning to fill a bubble completely.
An example
A teacher with one class of about thirty students gives a twenty-item check every Friday. One sheet per student is printed once as a class set, and the stack is graded with a punched overlay during the next class.
How to print this at 100% scale
- Open the PDF and choose File → Print.
- Set the scale to Actual size or 100%. Turn off “Fit to page”, “Shrink to fit” and any borderless option.
- Set the paper size to US Letter (8.5" × 11").
- Print one copy and check the four corner squares: each should sit about 5 mm (3/16 inch) in from the paper edge.
Why the fuss? A page scaled by even two percent moves every bubble slightly, and a camera grader measures where a bubble should be. Print at true size and the grid is where the grader expects it; print scaled and it may not be.
Printing note. One column leaves generous side margins. If your printer still clips the outer bubbles, check that it is not set to a borderless or "fit to page" mode, which scales the sheet down slightly.
How to use it
- Print one copy per student at 100% scale, single-sided.
- Have students fill in the header block first — name, date and class, and the Student ID grid if this sheet has one.
- For each question, fill one bubble completely. A half-filled bubble is a common cause of a mark being missed, and an X or a check mark can be another.
- Erase cleanly and completely. Smudged erasures can read as filled bubbles to a camera.
- Grade against an answer key — see the guide on making a test key overlay.

Frequently asked questions
How do I print this at 100% scale?
Open the PDF and choose Actual size or 100% — never "Fit to page" or "Shrink oversized pages". Those options quietly scale the sheet by a percent or two, and a mis-scaled grid is a common reason a camera grader misses marks. Check the corner squares: they should sit about 5 mm (3/16 inch) in from each edge.
Why one column instead of two?
One column keeps the questions in natural reading order, so students are far less likely to lose their place and bubble an answer on the wrong line. It also lets the bubbles print much larger than a two-column layout would.
Can I use this with a phone grading app?
Many camera-based graders read a regular grid of filled circles rather than a particular brand of form, but compatibility depends on the app and we have not tested any of them. Print one sheet, fill in a known pattern, scan it, and confirm the results before running a whole class set.
Can I edit the wording on the sheet?
The PDF is fixed by design, so it prints identically everywhere. For a different heading, more questions or a different choice set, use the free generator — it builds the same layout in your browser and downloads a fresh PDF.
Is 20 questions enough for a unit test?
It is enough for a short quiz and often too few for a unit test, where you may want a spread of topics and difficulty. For a unit test of thirty to fifty items, one of the longer single-page sheets is a better fit.
Why does this sheet have a Test line as well as a Name line?
The Test or Form line lets you write a version code, so two versions of the same quiz can be told apart when the sheets are mixed up. If you only run one version, leave it blank.
