Movies, music videos, and other content on DVD comes in a variety of formats including 1.33, 1.78, 1.85, 2.00, 2.35, 2.4, 2.5, and so on. However, these are not the only two formats that video material comes in. On the other hand, programs made for HDTV are in 16:9 format, which is 1.78 (16 divided by 9 = 1.78).

TV programs and videos intended for regular TV are done in 4:3 format, often denoted "1.33" since 4 divided by 3 = 1.33. On the other hand, movies and video come in many different aspect ratio formats. Here's the problem: any given TV or projector comes in its own native format-typically either 4:3 or 16:9. So HDTV's 16:9 is a rectangle that is, relatively speaking, horizontally wider than older TVs, which by comparison look almost square. Meanwhile, the new HDTV standard is 16:9, which is 16 units of width for every 9 units of height. That means the picture is 4 units wide for every three units of height. The standard TV that's been around since the mid-50s has an aspect ratio of 4:3. If you are new to the concept, when we talk about 16:9 or 4:3 or 2.35:1 formats, we're talking about the rectangular shape of the video image, or what is called its aspect ratio. The purpose of this article is to describe your options and help you decide which way to go. Which of these formats is best for you? It all depends on the trade-offs you want to make, and how you want to manage your home theater experience. You've got two good alternatives worth considering-going with a very large screen 4:3, or a super widescreen 2.35:1. But just because 16:9 has become the de facto standard, it doesn't mean it is right for you.

Almost all of the latest plasma and LCD flatscreen TVs are in the 16:9 format, and most video projectors intended for home theater are as well. For most people, that is absolutely right. These days conventional wisdom says that a new home theater should have a 16:9 projector and a 16:9 screen. NOTICE: THIS ARTICLE HAS BEEN REWRITTEN AND UPDATED.
