It is easy to become confused when trying to produce graphics for TV and video use. Picture aspect ratios and pixel aspect ratios may be of some help.

Most TV programmes in the UK are now broadcast in "letterbox" or widescreen format. Unfortunately, this can be a source of confusion as can the issue of anamorphic resizing. Widescreen TV in the UK may clear up some of the confusion.

For NTSC users Aspect Ratios and Frame Sizes may be helpful.
