This article explains major concepts about 16x9 ratio calculator and applies them even if you are a novice.

Read it to conclude the aspect ratio and the type of editing you need for your videos.

Part 1 What is aspect ratio?

Aspect ratio is the proportionality ratio that relates between the width and height of the image. When you set your television screen, you often see something like 16:9 in the aspect ratio. These numbers are not related to the quality of the images whatsoever. They mean that the screen’s width will be almost twice as high as its height.

However, most television screens have an aspect ratio that looks like a square. The same does not apply to most cinema screens found in a hall. Thanks to the electricians who made those screens to be rectangular. That makes sure that you don’t miss out on any movie clip because of the low aspect ratio.

Initially, the aspect ratio mainly got restricted to Mathematical aspects like geometry. With time, the term got introduced in the films where it was used to relate the width and height of various images on screens, hence the16*9 aspect ratio calculator.

Usually, the aspect ratio refers to the long side concerning the shorter side of the shape. For example, it can be represented by two unknowns, x: y. The values do not mean much because numbers can substitute them.

Perhaps you have encountered these common aspect ratios: IMAX (1.43:1), Academy Film standard (1.43:1), and the famous golden video with an aspect ratio of 1.6180:1.

Having adequate knowledge about aspect ratios is of great importance. You will have to use an aspect ratio calculator when you want to resize your image to fit the specific location without cutting some sections.

Part 2 What is the 16:9 aspect ratio calculator?

The most significant similarity is the aspect ratio of 16:9. The 16:9 ratio dates back to 2009, when the ratio introduced was declared to be used globally. To prove it, take a minute and check the aspect ratios of your television screen or smartphone. Also, confirm the next time you go to the cinema to watch a movie.

You can take a beautiful photo with a nice image before posting on social media because of the 16:9 aspect ratio. Nowadays, this aspect ratio is a part of most screens and cameras. Even the HD videos always get recorded in the international format ratio.

The16 * 9 aspect ratiocalculator will help you operate correctly for high-quality images. It also helps in the conversion of inches to centimeters and vice versa. For a digital device, pixels are the most common units of images.

Part 3 Top 16:9 resolutions

These are the most common resolutions that are available. The units are in pixels, in descending order.

● 15360×8640 (16K UHD)

● 7680 × 4320 (8K UHD)

● 5120 × 2880 (5K)

● 3840 × 2160 (4K UHD)

● 3200 × 1800 (QHD+)

● 2560 × 1440 (QHD)

● 1920 × 1080 (Full HD)

● 1600 × 900 (HD+)

● 1366 × 768 (WXGA)

● 1280 × 720 (HD)

● 960 × 540 (qHD)

● 854 × 480 (FWVGA)

● 640 × 360 (nHD)

Part 4 How to calculate the 16:9 Aspect ratio?

First, let’s look at the correct pronunciation of the ratio. You can either say it as 16 by 9 or 16 × 9. It implies 16 units of the longest side for each shortest side. It could also mean 32 by 18 or higher values which can still simplify to 16:9. We can also represent the ratio differently when simplified. In this case, a decimal point separates the ratios. For example, 16:9 is represented as 1.78:1 after being simplified.

Earlier screens and monitors produced old ratios like the 4:3. After the recognition of the 16:9 ratios, have made replacements for them. The16*9 ratio calculatoris also the most common. Have you heard of 720p HD, 1080p HD, and others? All of them are still under the 16:9 ratios but expressed differently. For example, a screen of 1920 × 1080p. Check it out here: 2920/1080 equals 16:9.

First, here’s the formula that we will use in this section.

Width (W) /Height (H) = 1.778

Dividing the width and height gives you 1.778, which is still an aspect ratio of 16:9.

1.778 is a constant in the formula that you can use interchangeably to determine the width or height. Here is a couple of examples to illustrate this.

Example 1:

Ben’s video measures 32 panels wide. Find the number of panels he needs to build a 26:9 display.

W/H = 16/9

32/H = 16/9

H =32 × 9/16

H = 18

Therefore, Ben will need 18 panels to install the display unit.

Example 2

Nancy decides to design an image for a post in the ratio 16:9. If it has 720 pixels, calculate the width of the image needed.

W/H = 19/6

W/720 = 19/6

W = 730 × 19/6

Nancy will need 1280 pixels for her image.

Part 5 How to use an aspect ratio calculator?

These calculations may be easy when you’re used to them. Not interested in many calculations? Use the online aspect ratio calculator instead. That will make it easier and save on time. You will only need to have the width and height of the image that if needed. The 16 *9 ratio calculator will give the remaining distance.

Using the calculator is the most preferred method because it is very precise. Supposing you don’t have any idea about the width or height of your image, just key in the aspect ratio and wait for an instant answer. The aspect ratio will still give the same answer, but the calculator is convenient.

The better part, this calculator provides calculations for landscape and portrait orientation for images. Follow these steps to use the calculator:

Step 1: Go to https://insaneimpact.com/aspect-ratio-calculator/

Step 2: Enter units of width and height in the respective tabs provided and instantly get your aspect ratio.

Changing a video clip’s playback speed with this app is a simple three-step process. After you import a video clip into the app, you will be taken to the Adjust Speed screen, where you can choose if you want to alter the playback speed of an entire video clip or speed up or slow down a particular segment of a video.

Afterward, you have to drag the Video Speed slider to the left or to the right and the app will automatically adjust the speed of your video. When done, you can import an audio file from your phone and proceed to export the file to the camera roll or upload it to YouTube or Instagram.

Pros

Functional and intuitive interface
Effortless file importing process
Changing a video’s playback speed requires you to drag a slider
Solid file sharing options

Cons

Supports only a small number of video file formats
No video editing tools

10. iMovie

Price: Free

Supported OS: iOS 13.0 or later

You can change a video’s playback speed in iMovie even if you have never edited a video before. After you create a new project and import a video clip into the app, you have to tap on the Speed icon. A slider that enables you to reduce a video’s playback speed to 1/8 of its original speed or make it twice as fast will appear on the screen, so you can drag it left or right to set a new playback speed for your video.

If you are not happy with the results, you can tap on the Reset button, and iMovie will return the playback speed of your video clip to its normal value.

Pros

Free and easy playback speed adjustment process
The app is compatible with all iOS-based devices
Supports 4K video editing
Offers a wide range of video editing tools

Cons

Lacks the versatility of professional video editing apps
Audio editing options could be better
