Sizing for Lyfjackets


Can I use this on a hardback book?

Yes if the hardback book does not have a dust jacket. We recommend adding a couple of extra mm to all your measurements to account for the thickness of the hardboard.

How do I measure a book?

Measurements are always in millimetres:

  • Measure the height of the front cover first from top to bottom in mm
  • Then measure the width of the front cover (from left to right) in mm
  • Now measure the width of the spine in mm
  • Lastly the total width = width of front cover x 2 + width of spine

If it is a hardback book add a couple of extra mm to all your measurements.

Is the code the height of the book?

Yes. Please note however that the total width determines whether you require a Standard or Longer Width Lyfjacket.

If the height if my book measures for example 198mm should I order code 198 or code 200?

Order code 198.
