Motion picture film and cameras, and later tele-

vision screens, were originally designed around 

a screen size that was almost square - it was 

one-third wider than it was high (another way to 

say this is that it had a width-to-height ratio, or 

aspect ratio, of 4:3. This ratio, 4:3, can also be 

expressed as 1.66:1.)

When widescreen movies using technologies 

like Cinemascope and Panavision became 

popular, new aspect ratios were used for them 

-  1.78:1, 2.35:1, and even 2.55:1. When high-

definition television was developed, a screen 

shape of 16:9, or 1.85:1, was selected as the  

best compromise for viewing widescreen movie 

images. 

When you watch widescreen movies on a 

standard 4:3 television, there are “black bars”  

on the top and bottom of the screen. This is 

often called a “letterbox” image. The alternative 

is called “pan-and-scan,” where the edges of the 

image are “cropped” off.

This system uses a widescreen 16:9, or 1.85:1 

display -  the same aspect ratio as high- defini-

tion televisions. This means that when viewing 

widescreen DVDs, these black bars are either 

non-existent, or greatly minimized.
