Understanding Proportional Sizing

Understanding Proportional Sizing for Wall Decals

When you’re ordering wall decals, it’s important to understand what “proportional sizing” means. This concept can be confusing, but it’s simple once you get the hang of it. Let’s break it down in the easiest way possible.

What Does “Proportional” Mean?

Imagine you have a photo that you want to make bigger. If you stretch it only in one direction (like only making it wider), the image will look weird and distorted. To keep it looking good, you need to make both the width and the height bigger at the same rate. This is what we call “keeping it proportional.”

Why Proportional Sizing Matters for Decals

Wall decals work the same way as photos. If you want your decal to look its best, you need to enlarge it proportionally. That means if you want it to be wider, it also needs to get taller, and vice versa.

Simple Example

Let’s say you have a square decal that’s 10 inches by 10 inches. If you want to double its size, you can’t just make it 20 inches wide and leave the height at 10 inches. That would stretch the image out and make it look odd. Instead, you need to make both the width and height 20 inches.

Here’s a simple step-by-step:

1. Original Size: 10 inches wide and 10 inches tall.
2. Double the Size Proportionally: 20 inches wide and 20 inches tall.

How to Know If You’re Doing It Right

To make sure you’re resizing proportionally, always multiply both the width and the height by the same number. If you want your decal to be three times bigger, multiply both the width and the height by 3.

Why Not Stretch One Way?

If you only change one dimension, your decal will end up looking stretched or squished. Imagine a picture of a person. If you make the picture wider without making it taller, the person will look very wide and short. If you make it taller without making it wider, they’ll look very tall and skinny. Neither looks good!

Tools to Help

Most design software and online tools have a setting to help you resize images proportionally. Look for options that say “lock aspect ratio” or “keep proportions.” This way, when you adjust one dimension, the other changes automatically to keep the image looking right.


– Proportional Sizing means changing the width and height at the same rate.
– Why It Matters: Keeps your decal from looking distorted.
– How to Do It: Multiply both width and height by the same number.
– Tools: Use design tools that offer “lock aspect ratio” settings.

By understanding proportional sizing, you can ensure that your wall decals look perfect no matter how big or small you want them to be. This simple concept keeps your designs looking sharp and professional.
