Size Matters! Measurements in InDesign for Print, ePub and Web

7-10 p.m.

6100 Center Dr. #1190, Los Angeles, California 90045

Opposite The Promenade at Howard Hughes Center



Research shows that a lot of designers still believe the myth that images for the web must be 72 ppi and that anything going to print must be 300 ppi. Further, few understand the peculiar way that the Adobe apps handle points vs. pixels-per-inch on output, or what is the best practice scale and resolution for a 10x30 foot vinyl when full scale is too big for InDesign Photoshop or Acrobat. Do you know the difference between ppi and dpi? Do you understand the different requirements among traditional line screen, stochastic screening and digital printing?


This LAIDUG meeting is a brush up on resolution and the measurement considerations one must deal with while working in InDesign (or its sister applications).


You will learn:

  • Units of measurement defaults, and the ones you should change right now!
  • Which units work best for which projects?
  • The three different meanings of “resolution” and why using the wrong one can mess you up.
  • The differences between “ppi,” “dpi” and “lpi.” What they mean. Why you have to know them.
  • What you see isn’t always what you get. Screen resolution vs. actual resolution, and why PDF can make you crazy.
  • “Effective” resolution and “Actual” resolution—what they are, why they matter, and some workflow tips to speed up your layout work.
  • Print vs. Web—two different mindsets.
  • The Great Myth of 72 ppi.
  • When to punt to InDesign’s best plugin: Photoshop.
  • The Great Gotcha: Points vs. Pixels when exporting from InDesign.
  • Megabytes vs megapixels: Why asking for a “high res photo” isn’t enough.
  • What does “divide by 8” have to do with the quality of a jpeg?
  • To upsample or not to upsample? Tips on handling undersized images.
  • Why working at 100% scale can slow you down, even when the document “fits” in InDesign.
  • Working to scale, and how to calculate it.
  • Small vs. large formats. How to avoid shooting yourself in the foot.
  • Electronic billboards and displays.
  • Choosing the right PDF output for a project.
  • Checking resolution with Preflight.


Bonus: Get a primer on image best practices for the most popular social media sites
