Printable Periodic Table Cheat Sheet
Free printable periodic table reference at exact scale — element groups, the first 20 elements, common ions, periodic trends and electron configuration on one page.
This periodic table cheat sheet is a text reference rather than the wall chart — it lists the main element groups and their members (alkali metals, alkaline earths, transition metals, halogens and noble gases), the first 20 elements with atomic number and mass, common ions and their charges, the direction of the periodic trends, and the orbital-filling order for electron configurations.
It prints at exact scale in real millimetres on A4, Letter or any size and pairs well with a full colour periodic table on the wall.
Printing at exact scale
Every sheet is drawn in real millimetres and prints at exact physical scale. For accurate output, set Scale = 100% (Actual size) and Margins = None in your browser's print dialog. Not sure your printer is honest? Run the printer ruler test first to confirm 50 mm really measures 50 mm.
Frequently asked questions
Is this the colour periodic table poster?
No — it's a compact text reference (groups, ions, trends, electron configuration). Use it alongside a visual periodic table.
What trends are described?
How atomic radius, ionisation energy and electronegativity change across a period and down a group.
Is it really free?
Yes. Every template on printsheet.io is completely free, with no sign-up, no account and no watermark. Generate as many sheets as you like.
How do I get an exact-scale print?
Choose your paper size, then in the print dialog set Scale to 100% or “Actual size” and Margins to None. The sheet is defined in real millimetres, so it prints at true size. Use the calibration ruler page to verify.
Which paper sizes are supported?
A4, A5, A3, A6, US Letter, Legal and Tabloid, in portrait or landscape. Pick the size that matches the paper loaded in your printer.
Can I save it as a PDF instead of printing?
Yes — choose “Save as PDF” as the printer in your browser's print dialog. The PDF keeps the exact millimetre dimensions.
