• 1.333:1 (4:3) : This aspect ratio was used commonly in the past for broadcast
and video but is now more readily associated with still image photography
and print. Common resolutions include 768 x 576, 1024 x 768, and 1600 x
1200. At the time of writing, the current generations of Apple iPad screens
use a 4:3 ratio.
• 1.500:1 (3:2) : This is the aspect ratio of a 35mm film and is also a typical
ratio used in photographic printing, a resolution such as 6 x 4 inches (or 10 x
15cm) being a fairly typical or common print size.
• 1.777:1 (16:9) : This is the current standard for High-Definition (HD) video
playback and broadcast TV. Common resolutions include 1280 x 720 (720p)
and 1920 x 1080 (1080p).
• 1.85:1 and 2.35:1 : These are two typical widescreen ratios used in the pro-
duction and presentation of big screen movies. Typical resolutions include
1828 x 988 and 3656 x 1976 for the 1.85:1 ratio and 2048 x 872 and 4096 x
1744 for 2.35:1.
Refer to the following diagram for classification of different aspect ratios:
The important thing that we need to note here is that the aspect ratio we set for our
final renders will naturally have a massive impact on the composition and staging
that we set up in our render views, hence the need to discuss the subject here first.
If we fail to set up our render views using the required ratio, then chances are that
