## What is meant by term aspect ratio?

Aspect ratio is a measurement unit to calculate the Width and Height relevancy for any screen and images. Aspect ratio specially used for finding and describing the dimensions of the rectangular and other screen shapes. Aspect ratios are shown in mathematical expressions as Width: Height format. For example, an LCD tv screen size 24 inches in width and 16 inches in height it would be an aspect ratio of 24:16 when we divide this equation from a lowest common factor which is 4 thus we get the 6:4 aspect ratio.

## How would aspect ratio be defined with examples?

Aspect ratio is defined as the calculator of screen and images dimensions, apparently, any screen may have the aspect ratio of 6:4 and 3:2 or relevant to this kind of ratio format, means that the width of the screen is wider fifty percent (50%) than its height. most of the modern screens have 16:9 aspect ratios while other less popular brands may be the longer or taller type of screen with various aspect ratios. For example, many LCD TV and computer monitors have 16:10 aspect ratios it means they are taller slightly than compare with standard HD displays. Lots of modern smart LCD and computer monitor screens frequently have extra long screens, therefore, any video played in landscape position on these devices doesn’t fit in the full-screen size and visible only in the centre rather than leaving black bars on top and down or side by side of the screen. For this reason, the aspect ratio of the video content is not accordingly wide hence doesn’t match with the aspect ratio of the screen.

## What are the available types of Projectors? How to choose the perfect one?

The are multiple types of projectors which are compatible with different screen types. It is essential to do some research before choosing one for yourself as not all projectors are perfect for all screen sizes. Read below to get a clear understanding of the same -:

### Square Format Screens

1.0 to 1.0 or 1:1 –  A 1:1  aspect ratio provides a perfectly squared screen format for overhead projectors (OHP) and is commonly used in educational institutions such as school and college classrooms. We strongly recommend for those have a similar requirement to opt for the OHP 1:1 slide projector which is best fitted with this screen format.

### NTSC or Video Format Screens

The 4:3 or NTSC  aspect ratio matches the same screen shape as the outdated (Non-HD) TV screens and computers (SVGA, XGA, UXGA) resolution. The dimensions of 4:3 are identical to attract the vision of few eyes on home TV screen viewers despite its longevity and need in the domestic market. Although 4:3  screens format is currently eliminated in acceptance of 16:9 and 16:10 aspect ratios for TV screens and projectors in both domestic and commercial designs. This is also ideal for schools or college classroom ambience. Thus, we strongly recommend going for OHP SVGA, XGA, UXGA projectors which are perfect for the presentations.

### Wide Format Screens

The 16:10 is the most popular aspect ratio for the latest modernized screen formats. It is immensely surpassing 4:3 aspect ratios out of fashion. The 16:10 aspect ratio screens have gained the market stack up to 90% till 2008. However, in late 2012, 16:10 aspect ratio too had started losing market share to 16:9 (HDTV) screens as this is the recent identical format of current TV screens and mobile gaming. For 16:10 screen sizes we recommend to choose the XGA (UXGA) projector.

### HDTV Format Screens

1.0 to 1.78 or 16:9 – The 16:9 aspect ratio is the High Definition TV (HDTV) format and this is the most advanced and updated format vastly used for the latest TV screen designs. This format is widely used in  TV screens and stand solo monitors. If you are using 16:9 projection screen then combine it with a native format projector to enjoy a Full HD movie experience.

### Cinemascope or Anamorphic Format Screens

1.0 to 2.35 or 2.35.1 – The Widescreen CinemaScope formats commonly called the 2.35.1 aspect ratios are superbly skilled and accurately combined with the anamorphic lenses. These products are accessible within 16:9 and 2.35.1 aspect ratios according to the current screen and projector market demands. For a magical home theatre experience and to create full cinematic effects we strongly recommend the 2.35.1 format screen if your application is totally home theatre Cinemascope presentations.
