How to Change Aspect Ratio on Amazon Prime

Are your Amazon Prime videos not fitting your TV or device screen correctly? It can be frustrating when movies and shows don't display properly. But don't worry, we have the solution for you! This guide will explain how to change aspect ratio on Amazon Prime. The aspect ratio is the size and shape of the video image. By changing it, your Amazon Prime videos will look great and fill up the whole screen. We'll cover what aspect ratios Amazon Prime uses and show you step-by-step how to adjust the aspect ratio easily.

Part 1. What is the Aspect Ratio for Amazon Prime?

Before we dive into the solutions, let's quickly understand what aspect ratio means. The aspect ratio refers to the proportional relationship between the width and height of an image or video. Common aspect ratios include

  • 4:3 (standard definition),
  • 16:9 (high-definition widescreen)
  • 2.35:1 (cinematic widescreen)

Amazon Prime supports various aspect ratios for uploaded videos, including 4:3, 16:9, 1.85:1, 2.35:1, and 2.39:1. However, the most widely used are 16:9 for HD videos and 4:3 for standard definition content.

Part 2. How to Make Amazon Prime Video Full Screen on TV

Unfortunately, the Amazon Prime Video app doesn't offer a built-in option to manually adjust the aspect ratio. However, you can change the display settings on your streaming device to alter the picture size. This process varies depending on the device you're using, but we'll guide you through the steps for popular platforms.

If your device has a "Fit to Screen" or similar option, you can use that to automatically adjust the aspect ratio to your screen's native resolution. However, if that feature is unavailable or doesn't work as expected, you need HitPaw Video Converter software to convert your videos to the correct aspect ratio beforehand.
