Resolution and Bit Depth Explained

Screen resolution
In the world of digital content creation, graphic design, and motion graphics, resolution and bit depth are crucial elements that directly influence your work’s visual quality. While many of us deal with these terms daily, truly mastering them ensures every detail in your project pops with clarity and vibrance. With many years in the design industry, I know firsthand how understanding these elements can make or break a project. Let’s dive into these concepts, explore their impact on design, and discuss how to make the right decisions for your next project.
Resolution: Pixels, Precision, and Practicality
Resolution refers to the number of pixels displayed in an image or video. It’s typically expressed as width × height (e.g. 1920×1080). For a designer, it’s not just about fitting more pixels into a frame but about ensuring clarity, sharpness, and precision at every frame size.
The physical size of your screen doesn’t matter, but how many pixels it can display determines the resolution. Have you ever played around with the display resolution of your computer and when you go to a smaller size, the screen seems to make everything bigger? This is because the display has less pixel space to show the image required on the screen.
Higher resolution increases file size and processing demand, so strategic decisions about when to use 4K or 8K are critical for maintaining efficiency in the production pipeline.

Pixels Per Inch (PPI)
Bit Depth
Pixels Per Inch (PPI)
Pixels per inch or (PPI) is the term used to calculate the image resolution on an image. It measures exactly what the term expresses; how many pixels are there in an inch? In the digital world, your photo will look fine even if the resolution you use is as low as 72 pixels per inch. However, if you are planning on printing the image, it is best practice to set it at 300 ppi or your image may print out blurry.
This is because a printer traditionally uses dots per inch (dpi). Unlike the computer screen which has square pixels, the printer outputs the ink in circular dots. If you’re using a smaller resolution, then those dots will leave some gaps and make your photo come out at a lower quality.
Bit Depth
Ever heard of the term 8-bit? That’s because there are 8 bits in one byte. Bits are the binary language that computers use (the 1’s and 0’s). Bit depth in an image can be quite complex to explain but to put it simply, each pixel will have a bit depth which determines how many colours it can have. An 8-bit image allows for 256 colours while a 16-bit depth or higher allows for an even greater value. Have I lost you already?
Whilst resolution is how many pixels you can fit into a screen, bit depth is how many colours you can fit on each pixel.
When producing animations, these two factors play a crucial role in creating seamless, immersive visuals. A high resolution ensures that animated elements remain crisp and clear, even when scaled or zoomed in. At the same time, high bit depth prevents colour banding in gradients, which is essential when animating skies, water, or smooth lighting.
For example, if you’re working on a 3D animation that involves realistic lighting effects, such as a sunset scene, 10-bit depth will ensure smoother colour blending. Using 4K resolution ensures the animation holds up across both big screens and smaller devices.
Let's Try Something!
Grab an A4 piece of paper and fold it in half; it doesn’t matter which direction. Now draw a grid of 5 by 10 in one half, and 10 by 20 in the other half. In the first half, you have made a screen with 5×10 pixel resolution while in the second half, you have made a 10×20 pixel resolution. The more pixels are on the screen, the more detail you can show. This is how resolution works.
How Resolution and Bit Depth Affect Motion Graphics
Motion graphics bring an added layer of complexity, as both resolution and bit depth directly influence how the animations will look when they scale or move between devices.
For smooth animations, such as dynamic brand identities or promotional videos, 4K resolution with a 10-bit depth strikes a great balance between detail and file size. Higher bit depths also come in handy when animating light effects or colour gradients, where subtle changes need to look seamless.
One thing I’ve learned over the years: perfection in design is about choosing the right tools for the right job. While it’s easy to default to the highest resolution and bit depth, this isn’t always the smartest choice. Managing your file sizes and render times becomes crucial, especially when juggling tight deadlines or delivering across multiple platforms.
For example, If you’re working on a branding animation for a client’s digital signage campaign, a 4K resolution and 8-bit colour might hit the sweet spot. But for a feature video with lighting transitions and gradient-heavy elements, bumping up to 10-bit could be worth the extra effort.
