Calculate Picture Ratio

PosterBurner's image aspect ratio calculator is a tool that takes your image and finds the best matching print sizes for your image. While this free tool you can select the image on your computer, tablet, or phone and the calculator will figure out the sizes that match your image best. Formula to find Aspect Ratio: Aspect ratio=a/b Pixels=a.b where, a = Width of the image b = Height of the image Calculation of Aspect ratio and number of pixels in a dimensional image is made easier. Aspect Ratio Calculator for Art. 1) For JPG files use the browse button below and select a file on your computer. The aspect ratio calculator will put the width and height values on the left hand side for you. Note:The value on the right can be anything you want! Centimeters, inches, or pixels. Or scan small film at 2700 dpi, print at 300 dpi, for 2700/300 = 9X size. If from full frame 35 mm film (roughly 0.92 x 1.41 inches), then 9X is about 8x12 inches (near A4 size). Film is typically small, requiring more scan resolution for more pixels for more print enlargement. A 4:3 ratio is typically used for TV displays, computer monitors, and digital cameras. For every 4 units of width, there are 3 units of height, creating a rectangular shape. An image sized at 1024 x 768 pixels or 8 x 6 inches fits a typical 4:3 ratio. The 16:9 ratio is mostly seen on presentation slides, computer monitors, or widescreen TVs.

Weights and Measurements

kilogram per inch (kg/in) is a non-metric measurement unit of linear or linear mass density.

An angle, in geometry, is defined by two rays a and b sharing a common starting point S, called the vertex. These rays can be transformed into each other by a revolution or rotation.

A tool for creating visually pleasing print borders using the golden ratio. You can calculate and preview the result for any picture or paper size.

Why did I start thinking about using the golden ratio for print borders? Actually, I was about to print one of my pictures. Looking at the screen preview of the print, I was trying to figure out visually pleasing borders.

Yes, I understand that this is a very subjective matter. But my goal was to create a repeatable approach for different picture and paper sizes.

In the past, I had used Martin Bailey’s print border calculations. He uses 10% of the shorter side of the paper as border size, but I find this too technical.

Calculate Ratio Of Two Numbers

Then I remembered having read about the golden ratio (represented by the Greek letter phi: φ, or 1 : 1.6180339887…) and how its proportions are considered aesthetically pleasing. So I checked if someone has already tried this out. The only related post I was able to find was about how to optimize the picture-to-border ratio. The post explains how to calculate a border size for a given image size, using the golden ratio. What I wanted was the exact opposite – to calculate the borders for a given paper size.

Calculate Picture Ratio Using

In the end, I developed my own formula to calculate the border size for any given paper size. I decided to make it available online so others can try and use it as well. The header image at the top of this post is an example of how the result looks like on ISO sized paper.

The original version of the calculator could only calculate the picture size for a given paper size. With the latest update, you can also calculate the paper size for a given picture size. A preview will give you an idea of how the result looks like. Additionally, you can choose to increase the lower border height for a more dynamic off-center look or to leave some space for text.
