Our resolution scale calculator helps resize digital resolutions and provides other resolutions that maintain the aspect ratio in its dynamic resolution scale chart.

You can easily up-scale or down-scale your resolution by entering your resolution scale as a percentage or by inputting its aspect ratio in the original resolution field and scaling it up.

If you're calculating upscaled resolution for image printing, you can convert your **resolution to print size** based on its **PPI (pixels per inch)** and get its framing dimensions using our picture frame calculator.

🔎 Check out our pixels to print size calculator and our PPI calculator to learn more about these topics.

## Definition and purpose of resolution scaling

The act of resizing a resolution to transform how it is displayed on the screen's pixels is known as resolution scaling.

When down-scaled, the display resolution takes up more pixels for each displayed object, providing a zoomed-in display. And when up-scaled, the display resolution takes fewer pixels for each displayed object, providing a zoomed-out display.

**Image resolution scaling**

Image resolution scaling works in an inverse manner to display resolution scaling. When resizing an image resolution while keeping the resolution of the display constant:

**Down-scaling**causes the pixels in the image to come closer, sharpening the image and reducing its size.- And when
**up-scaling**the image resolution, its pixels expand, thus blurring or pixelating the image and increasing its size.

💡 **Video resolution scaling** works similar to image resolution scaling, where up-scaling the video resolution increases its size, but the quality drops, and the details become blurry.

**Game resolution scaling**

By default, video games run at fullscreen with their objects rendered at 1:1 to match the display resolution. We can down-scale their render resolution to increase the game's performance, but at the cost of visual quality, or up-scale the render resolution to improve the visual quality, but at the expense of performance.

As an example, let's say your native screen resolution is 2560×1440. You can downscale your favorite game's render resolution to 1920×1080 to experience a significant boost in the performance. However, you'll need to increase the sharpening and use anti-aliasing to improve your game's visual experience.

## How to scale a resolution using the resolution scale calculator?

Here's how you can use our calculator to scale your resolution for images or videos:

Enter the original

**resolution width**and**height**of your object, i.e.,*1920×1080*.Input the percentage by which you want to

**scale**your object's resolution, i.e.,*25%*.If you want the calculator to

**down-scale**your resolution,**reduce**the percentage.**Increase**the percentage if you want the calculator to**up-scale**your image resolution.

The calculator will then display the scaled values, e.g., when scaling

**1920×1080**resolution by**25%**, we get**960×540**.

🙋 After calculating resolution upscale or downscale values, the calculator gives their **aspect ratio** and a **resolution scale chart** (in the `Advanced mode`

).

## How to calculate the resolution scale percentage?

To calculate the resolution scale percentage, enter your **scaled resolution** after entering the **original resolution**. The calculator will automatically calculate the scale percentage whilst showing the dynamic resolution scale chart.

For example, if you wish to find the percentage scale of **1440p** resolution from **1080p**, enter *1920×1080* in the original resolution, then the scaled resolution section to be displayed. Enter *2560×1440* in the scaled resolution. You'll get a percentage scale of **177.8%**.

🔎 As an additional feature, you can measure the **physical**, or **print size**, of your scaled resolution by entering the **PPI** (pixels per inch) in the **pixel density** field, under the *digital to physical dimensions* section.

## How to manually scale or resize a resolution using the formula?

We use the following formulas to manually scale the *width* and *height* of a resolution:

$\small\quad\text{Width}_{\text{(scaled)}} = \sqrt{\frac{\text{pixel}}{\text{W'ratio}}},\\[1.5em]\quad\text{Height}_{\text{(scaled)}} = \sqrt{\frac{\text{pixel}}{\text{H'ratio}}},$Width(scaled)=W’ratiopixel,Height(scaled)=H’ratiopixel,

where:

- $\text{pixel}$pixel is the
**total number of pixels**in the resolution; - $\text{W'ratio}$W’ratio is the
**ratio**obtained by dividing the resolution's*height*by its*width*; and - $\text{H'ratio}$H’ratio is the
**ratio**obtained by dividing the resolution's*width*by its*height*.

**Here's how to use the formula to scale a resolution by percentage:**

- Find the required
**pixel**percentage by multiplying the original resolution**width**by its**height**. Then, divide the result by 100 and multiply it by your**scale value**.

$\small\quad\text{pixel} = \text{width}\times\text{height}\times\frac{\text{scale}}{100},$pixel=width×height×100scale,

where:

- $\text{scale}$scale - The required percentage value to up-scale or down-scale the resolution.

**E.g.,** if we want to scale 1440p resolution down to 50%, we first find the number of pixels in a 1440p resolution:

$\small\quad\begin{align*}\text{pixel} &= \text{width}\times \text{height}\times \frac{\text{scale}}{100}\\[1.0em]&= 2560\times 1440\times \frac{50}{100}\\[1.0em]&= 1,\hspace{-0.04cm}843,\hspace{-0.04cm}200\end{align*}$pixel=width×height×100scale=2560×1440×10050=1,843,200

- Divide the resolution's
*height*by its*width*to find the**W'ratio**and the*width*by its*height*to find the**H'ratio**.

$\small\qquad\text{W'ratio}= \frac{\text{height}}{\text{width}}\\[1.5em]\qquad\text{H'ratio}= \frac{\text{width}}{\text{height}}$W’ratio=widthheightH’ratio=heightwidth

**E.g.,** using the values of a 1440p resolution gives:

$\small\qquad\begin{align*}\text{W'ratio}&= \frac{1440}{2560}\\\\&= 0.5625\end{align*}$W’ratio=25601440=0.5625

$\small\qquad\begin{align*}\text{H'ratio}&= \frac{2560}{1440}\\\\&= 1.7778\end{align*}$H’ratio=14402560=1.7778

- Divide
**pixel**by the**ratios**and take a**square root**of the result to find your scaled resolution.

$\small\quad\text{Width}_{\text{(scaled)}} = \sqrt{\frac{\text{pixel}}{\text{W'ratio}}}\\[1.5em]\quad\text{Height}_{\text{(scaled)}} = \sqrt{\frac{\text{pixel}}{\text{H'ratio}}}$Width(scaled)=W’ratiopixelHeight(scaled)=H’ratiopixel

**E.g.,** by using the values of *pixel* and *ratios* from Step **1** and **2**, we can scale a 1440p resolution down to 50%:

$\small\quad\begin{align*}\text{Width}_{\text{(scaled)}}&= \sqrt{\frac{\text{pixel}}{\text{W'ratio}}}\\\\&= \sqrt{\frac{1,\hspace{-0.04cm}843,\hspace{-0.04cm}200}{0.5625}}\\\\&= 1,\hspace{-0.04cm}810\\\\\end{align*}$Width(scaled)=W’ratiopixel=0.56251,843,200=1,810

$\small\quad\begin{align*}\text{Height}_{\text{(scaled)}}&= \sqrt{\frac{\text{pixel}}{\text{H'ratio}}}\\\\&= \sqrt{\frac{1,\hspace{-0.04cm}843,\hspace{-0.04cm}200}{1.7778}}\\\\&= 1,\hspace{-0.04cm}018\end{align*}$Height(scaled)=H’ratiopixel=1.77781,843,200=1,018

Thus, if we down-scale **2560×1440** to **50%**, we get a **1810×1018** resolution.

🙋 If we up-scale *1920×1080* resolution, also known as **1080p** or **FHD**, to *177.8%*, we get *2560×1440*, known as **2K** or **1440p**. Inversely, if we down-scale the 2K resolution to 56.25%, we get FHD.

## FAQ

### How do I calculate image resolution scale?

To calculate image resolution scale:

- Divide the width of your image by its height to find the image
**ratio**. - Multiply your preferred height with this
**ratio**to obtain your image width.

If you have a preferred width instead of height, swap them with each other to find the resized image ratio and the new height.

### What are standard laptop screen resolutions?

Here are some standard laptop screen resolutions:

**16:10 aspect ratio resolutions**

- 3840×2400
- 3072×1920
- 2560×1600
- 1920×1200

**16:9 aspect ratio resolutions**

- 2560×1440
- 1920×1080
- 1600×900
- 1366×768

### What is PPI?

PPI stands for **pixel per inch**.

It is how we understand the sharpness of a display, thus helping us measure its overall quality. PPI tells us the pixel density, i.e., the number of pixels packed in an inch of the display. Higher PPI means there's more room for information on the display.

### What is resolution scale?

Visually transforming a resolution across the display pixels is known as resolution scaling, e.g., keeping the resolution ratio the same and resizing an image, video, or display by up-scaling or down-scaling their resolution.

### What is the percentage scale of 1080p from 1440p?

If we down-scale 1440p by 56.25%, we get 1080p. And we up-scale 1080p by 177.78%, we get 1440p.

To get these values:

- Multiply the width and height of a resolution, i.e., 2560 by 1440 and 1920 by 1080.
- Divide both results with each other, i.e., 2,073,600 / 3,686,400.
- Multiply the end result by 100, i.e., 1.778 × 100 = 177.78%.
