    bitmap billboard

    Chemol Level 1

      Does anyone know what the typical (highway) billboard size is, and what is typical resolution needed for pixel based imagery?  I have heard anywhere from 75 ppi to 150 ppi - thoughts?

          Don't know their size, but I heard the resolution was as low as 25 ppi.

            The average size is 48' x 14' and at full size they are usually around 20ppi. But rarely do you work full size, most of the time it's to what they call 1/4 scale, confusing, because what they mean is 1/4" = 1'. I would call that 1/48 scale. They always state the dimensions height first and then width so they call their standard size 14x48. Must be a holdover from the pre-PS days.


            The specs for large signage are all over the map so you need to get good information from the vendor before you start.

              Wow.. That low eh?  I'll need to look into it with the output provider.


              Thank you!

                Thank you Paul.  That's exactly the info I was looking for, very helpful before I tackle this project.  I was starting to freak out wondering how I would interpolate a photo that size  - I was thinking I would have to increase it to 150 ppi.  I'll verify once I find out who the client is going to use as a vendor ~ thanks so much!
