How to Create Large Print Sudoku Books for Seniors on Amazon KDP
Large print Sudoku books are an evergreen goldmine on Amazon. Seniors, visually impaired puzzle fans, and travelers prefer large grids with generous spacing for notes. Here is how to create a compliant, high-converting large-print Sudoku book from start to finish.
What Qualifies as 'Large Print' on Amazon?
To legally and ethically use the 'Large Print' badge on Amazon KDP, your book must conform to American Council of the Blind standards: - Font size must be at least **16 points** (preferably 18pt to 22pt for puzzle numbers). - High contrast: Pure black numbers on white background with thick grid lines. - Maximum **1 or 2 puzzles per page** on an 8.5" × 11" trim size.
Step 1: Grid Dimensions and Line Weights
A standard 9×9 Sudoku grid on an 8.5" × 11" page should measure approximately 6.5" × 6.5". - Major 3×3 box boundaries should use a 2pt or 2.5pt stroke thickness. - Minor cell borders should use a 0.75pt stroke thickness. - Numbers inside the cells should be centered and rendered in a clean sans-serif typeface like Inter or Roboto.
Step 2: Difficulty Balancing
Seniors love challenges, but unfair puzzles cause frustration. Structure your book with progressive difficulty: - 40 Easy Puzzles (Warm-up) - 40 Medium Puzzles (Daily Brain Workout) - 20 Hard Puzzles (Weekend Challenge) Always clearly mark difficulty levels at the top of each page.
Step 3: Compiling the Solution Section
Never make seniors squint at microscopic answer keys. Place solutions in a clean 4-up grid (4 solutions per page) with bold cell numbers and clear page cross-references.
