# Image Size Proportion Calculator

Image aspect ratio and resizing calculator Work out image ratios and scale proportionally This is a simple calculator to help you work out the aspect ratio of an image, and the size of that image when it's resized, keeping the same proportions.

Proportion on the other hand means there should be all over balance across the different parts of the body; for example, the legs should be a certain size compared to the arms. You often see physiques where the top part of the body is massive but the legs are under-developed. A free on-line calculator that estimates sample sizes for a proportion, interprets the results and creates visualizations and tables for assessing the influence of changing input values on sample size estimates. Having just tried this code (found it else where while searching for the same basic problem), it doesn't actually do the job if you start out with an image that has both width and height that are larger than the maximums - you need to apply either the first or second scaling depending on which dimension of the original image is greatest, otherwise you end up with one of the dimensions being.

### Image Size Formula:

Width = Original Width * ( Percentage / 100 )
Height = Original Height * ( Percentage / 100 )
Derive Width or Height Percentage by:
Percentage = Future Size / Original Size

### Image Size Definition

Use our free online Image Size Calculator to do your image size calculations simple and easy! With so many uses possible for digital images, it’s important you get the size right. Sizing up your image in the wrong way could lead to images not fitting the use you have for them, or images that are unattractively stretched or squeezed.

### Why Image Size is Important

Digital images use pixels to display their content. Each pixel is like a building block of an image; these building blocks are the base unit that make up what you see in a picture. That means it’s important to use the correct size if, for instance, you are scaling an image for use on a web page.

If you use an image that’s too large for the space it’s in, it will result in unsightly aliasing, or jagged looking edges. If you use an image that’s too small and needs to be stretched out, it will result in ugly pixellation, where the base pixels become large enough to be seen individually.

If you need to resize an image to a particular size, it’s important to choose the right percentage to scale your picture up or shrink it down. This calculator is very useful for choosing just the right size to scale your image to.

### How to Use the Image Size Calculator

This calculator allows you to enter the following components:

1. Original height and width
2. Scaling percentage
3. Future height or width

Using the image size calculator is easy:

1. Enter the height and/or width of the image you need to scale.
2. Either enter a percentage that you wish to scale the image to, or enter the final size you wish your image to be in height, width, or both.
3. Click “calculate”

After submitting your figures, your calculations will display on the screen. If you entered a percentage, the new height or width will be displayed. If you entered a future height or width, the percentage needed to scale to that size will be displayed.

### Things to Remember When Scaling Images

-Scaling an image larger will make the individual pixels of that image larger, as well. This will result in pixellation if you scale it too large.
-The height or width of your image in pixels is not the whole story. Use your image processor program to check what your image’s resolution, or dots per inch, is if you intend to print your image out. Some images may have the same number of pixels, but if the resolution is 72 DPI, it will print on paper much larger than if the resolution is 300.

### How to Calculate Image Size

Let's be honest - sometimes the best image size calculator is the one that is easy to use and doesn't require us to even know what the image size formula is in the first place! But if you want to know the exact formula for calculating image size then please check out the 'Formula' box above.
