Your Walls, Your Pattern: How to Use Our Custom Wallpaper Tool in 4 Easy Steps
Customize and Personalize
The decision to hang wallpaper in your home can feel like a major commitment. Covering an entire room, or even just an accent wall, is a big design move.
Often, the hardest part is simply choosing a design. Browsing through hundreds of pre-made patterns can quickly lead to decision fatigue.
That is why we created the custom wallpaper pattern tool at BIG Wall Décor. Instead of settling for someone else's vision, you can upload any seamless pattern or generate your own from scratch using our built-in AI generator.
Here is exactly how to use our tool to create the perfect look for your space.
Step 1: Source or Generate Your Custom Pattern
You have complete creative control over your walls, and getting your design into the tool is incredibly simple:
-
Upload your own file: If you already have a seamless pattern or a high-resolution photograph you want to repeat across the wall, you can upload it directly.
-
Generate with AI: Can’t find a pattern that checks all your boxes? Use our integrated AI generator. The options are endless. You can prompt the specific elements, choose the art style, and dictate how large or small the graphics should be.
-
Prefer a non-AI approach? If you want to design a pattern yourself without AI assistance, check out how to make a seamless pattern for free!

Step 2: Dial In Your Specific Layout Requirements
Our custom tool gives you the exact same professional material options as our standard wallpaper collections. Here is how to configure your layout:
-
Choose your repeat type: This dictates how your pattern blocks line up next to each other.
-
Pro Tip: Some patterns will misalign if you change how they repeat. Always double-check the visual preview to ensure your pattern aligns perfectly before checking out.
-
-
Select the repeat size: You can scale your pattern repeat anywhere from 2 inches up to the full width of the panel.
-
Pro Tip: Keep an eye on the quality indicator at the top of the page when scaling up. Making a pattern too large can sometimes lower the image sharpness.
-
Step 3: Enter Your Dimensions and Materials
Once your design is locked in, it’s time to fit it to your physical room:
-
Input your measurements: Enter your exact wall dimensions and select your preferred panel width. Don't sweat the math! We automatically add a few inches of excess slack to each panel so you won't run short during installation.
-
Select your application type: Choose between Peel & Stick or traditional Paste-the-Wall application.
-
Pick your texture: Each application style comes with unique premium material and texture options to give your wall the perfect finish.
Once you've made your selections, just hit "Add to Cart" and you are ready to go.
