The Complete Size Illusions Printables Bundle

All six size illusion printable packs in one download, A4 and US Letter, plus a bundle guide: the drawing sheets, puzzle pack, experiment cards, lab log, kids’ worksheets and poster set. $12.99 instead of $26.94 for the six packs bought separately.

What’s inside:

- Draw Your Own Size Illusions: Step-by-Step Sheets

- Size Illusion Puzzle Pack: Measure, Spot & Solve

- Make-and-Test Size Illusion Experiment Cards

- Illusion Lab Log: Measure-It Record Book

- Don’t Trust Your Eyes! Kids’ Size Illusion Worksheets

- A 3-page bundle guide

Pages: 68 across the six packs, plus a 3-page bundle guide (A4 and US Letter), all in one zip.

Printing: Print at 100% / actual size on A4 or US Letter, so the drawings keep their true measurements. Inside pages use light backgrounds and print well in black and white; covers are dark, so start from page 2 to save ink. Fill-in pages (logs and surveys) can be printed as often as you need for your own family or class.

Every fact is checked against Michael Bach’s Optical Illusions & Visual Phenomena, Encyclopaedia Britannica and the Exploratorium (checked 31 Oct 2026), and the sources are listed on each pack’s credits page. Photos are public-domain or CC0 images via Wikimedia Commons; all illusion drawings are our own. Drawings, puzzles and layouts are REALLYBYTE’s own work. Not endorsed by Michael Bach, Britannica or the Exploratorium.

Licence: personal and single-classroom use. You may print as many copies as you need for your own family or your own class, and share it with your class through a password-protected platform.
