Math Practical Problems for Animators Figuring Out Aspect Ratios

How does an animator decide on the physical size of their project? What is an aspect ratio? What are standard aspect ratios for different media? (HDTV, video, social media, web banner) Where can you find these out? Why is figuring out the aspect ratio before you start a project important?

Read the Scenario Your teacher will give you a handout with the scenario on it. This scenario is something everyone in media needs to figure out for every job. Once you have figured out project requirements, you can figure out your aspect ratios.

A Pro Works With Data A pro doesn’t guess – they research, ask around, and gather real data. Jamal (in the scenario) needs to find standard industry sizes in order to figure out his aspect ratios. He can refer to manuals or search on the Internet. Once he does figure out his size, the information is good for the next project, but he must still make sure the data is current.

What are the Project Specs? Jamal is creating an animation that will be shown on HDTV What is the standard aspect ratio for HDTV? What is the unit of measurement?

Problem 1: Area Length time width = Area Make sure your unit of measurement is consistent. Use professional units (mm, cm, pixels).

Problem 2: Using It in an App If your application doesn’t allow you to use the aspect ratio you want, you have to decide on the nearest option. Always choose the next larger option. Figure out the lowest common denominator to find out what the option’s aspect ratios are.

Final Thoughts When needed, round up to the next highest number. Use standard industry sizes when starting a new job. Why is this important? An old carpenter’s saying is measure twice and cut once. Why is this applicable to animation? Why is precision important?
