Pick your preferred material, then enter your wall's total width. No need to account for doors, windows, or openings — we'll do the math and give you an instant panel count.
When you're ready to place your order, select from four panel height options: 4 ft, 8 ft, 9 ft, or 10 ft.
Your support means the world to us. As a small, family-run business, every order is printed on demand — and we're excited to help transform your space!
(Please note, our wallpapers come in double rolls; for example, 3 double rolls will provide you with 6 individual panels.)
Still have questions? If you’re working with a slanted wall, tricky angles, or obstacles like a bathroom vanity, feel free to reach out. Whether you need guidance or a custom size, just send us your wall measurements and we’d be happy to help you figure it out!
How to Measure Your Wall
1. Measure the Full Wall Area
Use a tape measure to get the total width and height of your wall in inches.
Ignore any windows, doors, or outlets—our panels will be trimmed around them during installation.
2. Understand How Panels Align
All wallpaper panels are sold in double rolls—meaning each order contains two individual panels. Panels are installed from the top down to ensure a smooth, professional finish.
While wallpapers are made with repeating designs, it’s important to make sure all panels are facing the correct direction before installation. This helps ensure the pattern aligns properly and flows seamlessly from left to right across your wall.
3. Panel Dimensions
Each of our wallpaper panels is available in four standard heights: 4 ft, 8 ft, 9 ft, and 10 ft.
Choose the height that best suits your project at checkout.

Learn moreThe First Yes: How the Garden Room Set the Tone for the Greencrest Collection
The Garden Room wallpaper at Greencrest Manor became more than a design choice. It became a blueprint for how we approach custom wallpaper for meaningful spaces. From selecting a floral pattern that echoes the surrounding gardens to choosing peel and stick wallpaper for flexibility and seasonal use, every detail was intentional. If you’re designing a wedding venue, historic home, or light-filled gathering space, this is your reminder that wallpaper should elevate what already exists. The right pattern does not require a full redesign. It completes the room, enhances natural light, and supports the emotional experience of the space. The Garden Room was our first yes at Greencrest. And sometimes, that first yes sets the tone for an entire collection.

Our first visit to Greencrest during the quiet season felt like the real starting point. With autumn color still lingering on the trees, we walked the manor slowly, studying how each room functions and where wall design could add depth without overwhelming the space. The focus wasn’t on locking in choices, but on understanding the rhythm of the home, honoring its past, and gathering insight to shape a collection inspired by nature, heritage, and thoughtful design.
