As of March 2025, the best-selling photo wallpapers are heavily influenced by current interior design trends, particularly those emphasizing nature-inspired, bold, and personalized designs. Based on the latest trends and popular products, here’s what stands out:

1. Nature-Inspired and Botanical Designs: Photo wallpapers featuring forest motifs, tropical landscapes, floral patterns, and animal illustrations are dominating the market. These designs, such as lush greenery, oversized botanicals, and wildlife (e.g., deer, birds, or jungle scenes), are highly sought after for creating immersive, calming, and adventurous atmospheres in living rooms, bedrooms, and kids’ rooms. Brands like Komar, AGdesign, and Consalnet highlight these as top sellers, with designs like forest murals and tropical wallpapers leading the pack due to their timeless appeal and ability to transform spaces.
2. Kids’ Room Space and Adventure Themes: Photo wallpapers with cosmic or astronaut exploration themes, like the "Cosmic Adventure WALLPAPER: Astronaut Exploration Mural for Kids' Bedrooms" are incredibly popular. These murals, often featuring astronauts, planets, and starry skies, cater to children’s imaginations and are among the best-selling options for nurseries and playrooms, as noted by brands like Wizard & Genius.
3. Geometric and Modern Patterns: For a contemporary look, geometric and abstract photo wallpapers remain best-sellers, especially in home offices and modern living spaces. These designs often incorporate bold colors or neutral tones (like beige and earth tones) to create a minimalist yet striking focal point.
4. Textured and Faux Effects: Photo wallpapers mimicking textures like grasscloth, silk, or faux materials (e.g., brick, wood, or marble) are also trending. These add depth and elegance, making them popular for dining rooms, powder rooms, and hallways. Silk and metallic finishes, such as gold or silver, are particularly noted for their luxurious appeal in 2025.
5. Custom and Personalizable Murals: There’s a growing demand for custom photo wallpapers, where customers can upload personal photos or choose from vast libraries of high-resolution images (e.g., landscapes, cityscapes, or art).

These trends are driven by a shift toward maximalism, sustainability, and personal expression in home décor, as well as the ease of installation with peel-and-stick or non-woven options. If you’re looking for specifics, nature-inspired murals, space-themed kids’ wallpapers, and textured designs are consistently topping sales lists in early 2025, according to interior design insights and customer preferences.
