Spiral Bound Layouts: Spine Width & Bleed Sizing Rules
Designing a spiral bound workbook? Learn coil size calculations, inner margins, and print bleed guidelines.
Eleanor Vance
Head of Digital Production
"Spiral and coil bound books are popular for workbooks, journals, and manuals. Formatting these books requires unique margins to prevent page holes from cutting text."
Core Key Takeaways
- Setting Wide Inner Margin Hole Spacing
- Calculating Coil Size and Spine Width
- Designing Cover Wraps for Coil Binding
1. Setting Wide Inner Margin Hole Spacing
Coil punches cut deep into pages. Set inner margins to a minimum of 0.75 inches to ensure text stays clear of punch holes.
- Keep inner page margins at 0.75" minimum to avoid coil holes.
- Calculate spiral coil size based on page count and paper weight.
- Avoid placing critical design details near punch lines.
2. Calculating Coil Size and Spine Width
Select coil sizes (ranging from 6mm to 50mm) based on page count and paper thickness to ensure pages turn smoothly.
