How to Set Font Size to Print A4 Document as 11-Point on A5 Paper
Question details
The user wants to know what font size to apply to an A4 document so that the text measures exactly 11 points when the document is scaled down and printed onto A5 paper.

- Scenario
- Creating a standard A4 document but intending to print it on smaller A5 paper (for booklets or flyers), requiring the final printed text to remain legible at 11 points.
- Observed behavior
- The user needs the mathematical scaling factor and exact font size to input before printing to ensure the text shrinks to the desired 11-point size on the physical A5 output.
Verify that your printer supports A5 paper sizes and has a 'Scale to Paper Size' or 'Fit to Page' option in its printing preferences.
Calculate and Apply Proportional Font Sizing
Adjust the font size in your original A4 document to approximately 15.5 or 16 points to account for the A5 reduction.
A5 paper is not 50% of the linear size of A4; it is actually about 70.7% of the size in terms of width and height. Because font sizes are measured linearly, you must divide your target font size (11) by 0.707 to find the starting size.
The calculation results in approximately 15.55 points. If your word processor allows half-point increments, use 15.5. If it only accepts whole numbers, use 16 points.
Open your A4 document and press 'Ctrl + A' on your keyboard to select all the text.
Navigate to the 'Home' tab. Click inside the Font Size dropdown box, type '15.5' or '16', and press Enter.
Go to 'File' > 'Print' to open the print dialog. Look for the paper scaling or zoom options, and set 'Scale to Paper Size' to A5.
Select to print only the first page. Review the printed output to ensure the text scaling and printer margins match your expectations.
Easily Scale and Print Documents with WPS Office
WPS Writer offers intuitive built-in page scaling and flexible layout features. Whether you are printing A4 to A5 or creating custom booklets, WPS handles the scaling automatically, removing the guesswork from document preparation.
- 1. Open Your Document: Launch WPS Writer and open the A4 document you wish to print.
- 2. Access Print Settings: Click the 'Menu' button in the top left corner and select 'Print', or simply press 'Ctrl + P'.
- 3. Configure Paper Scaling: In the Print dialog box, locate the 'Zoom' section. Under the 'Scale to paper size' dropdown menu, select 'A5'.
- 4. Print the Document: Load A5 paper into your printer tray and click the 'Print' button. WPS will perfectly scale the content to fit the new page size.
Frequently Asked Questions
Why is A5 considered 70.7% of A4 instead of 50%?
While A5 paper has half the total surface area of A4, its physical dimensions (width and height) are reduced by a factor of the square root of 2 (approx. 1.414). Therefore, the linear length of A5 is roughly 70.7% of A4. Since font size measures linear height, you scale by 70.7%.
What if my word processor doesn't let me type 15.5 for a font size?
If your software strictly limits font sizes to whole numbers, round up to 16 points. When reduced to A5, the text will appear as roughly 11.3 points, which is nearly indistinguishable from 11 points and highly readable.
Can I just change my page setup to A5 before I start typing?
Yes. If you change your page size layout to A5 before you create the document, you can simply use an 11-point font directly. This provides a true WYSIWYG (What You See Is What You Get) experience and removes the need for scaling calculations at print time.
Does scaling to A5 change my document's line breaks and page numbers?
No. When you use the printer's 'Scale to Paper Size' function, the software treats the document exactly like an A4 layout and simply shrinks the final image. Your line breaks, pagination, and formatting remain completely unchanged.
