Technical Specifications

Manufacturing a book in the A5 (5.83" x 8.27") format requires adherence to strict global printing protocols. The following specifications ensure that your file remains "Print-Ready" across major distribution networks like Amazon KDP and IngramSpark.

Protocol Standard Value
Trim Size 5.83 in x 8.27 in
Bleed Width (Total PDF) 5.955 in
Bleed Height (Total PDF) 8.52 in
Outside Margins Min 0.25 (6.4 mm)

Bleed Protocol & Logic

When your interior design includes background colors, images, or elements that extend to the edge of the physical page, you must apply the **Full Bleed Protocol**. This extends your document dimensions to accommodate the physical trimming cycle.

To calculate the bleed requirements for the A5 (5.83" x 8.27") format, we apply a standard 0.125" (3.2 mm) extension to the width and top/bottom edges. This results in a final PDF page size of 5.955" x 8.52".

Internal Gutter Margins

Internal margins, or "gutters," vary based on the total page count. For a A5 (5.83" x 8.27") edition, ensure that your text block remains within the following safe zones:

  • 150-250 Pages: 0.5" (12.7 mm) Gutter
  • 250-400 Pages: 0.625" (15.9 mm) Gutter

Precision Audit

While these specs are verified for 2025 manufacturing, always verify your exact page count against the Spine Width Calculator before finalized your cover design.
