How to Use This Calculator
  1. Enter the text block height and width in millimeters.
  2. Select the endpaper type: simple fold (tipped on), sewn in, or multi-section for fine binding.
  3. Enter the number of books to calculate total endpaper sheets needed.
  4. Read the sheet width and height in mm (and inches) — these are the cut dimensions for each endpaper sheet.
  5. Note that the sheet width is approximately twice the block width plus a hinge allowance for folding.
  6. Use the total area in cm² to estimate how much decorative or coordinating paper to purchase.

How this is calculated

Worked example, using the default values

  1. Identify Input Parameters
    4 parameters
    Book block height (mm) = 210, Book block width (mm) = 148, Endpaper type = 1, Number of books = 1 = 4 input(s) provided
  2. Calculate Sheet width
    Sheet width = 2 * blockWidthMm + hingeAllowanceMm
    301 = 301
  3. Calculate Sheet height
    210 = 210
  4. Calculate Sheet width
    Sheet width = sheetWidth / 25.4
    11.85 = 11.85
  5. Calculate Sheet height
    Sheet height = sheetHeight / 25.4
    8.27 = 8.27
