Overview

Amazon now supports 3D product content across multiple categories, giving customers an interactive way to evaluate items before purchasing. Sellers who want to leverage this feature must follow specific technical guidelines to ensure their 3D models meet Amazon's standards for quality, accuracy, and compatibility. Understanding these requirements upfront can save significant time and prevent costly rejections during Amazon's quality assurance review.

Key Points / What Sellers Need to Know

• File format matters — Amazon accepts 3D models in GLB and glTF formats only. GLB is the recommended option because it bundles all textures and mesh data into a single binary file, simplifying the upload process.
• Real-world accuracy is mandatory — Models must be built to real-world scale, meaning the dimensions of your 3D asset must match the actual assembled product dimensions. Inaccurate sizing will delay publication.
• Texture quality has strict bounds — All texture files must be in PNG or JPG format, with resolutions between 2K (2048 x 2048 pixels) and 4K (4096 x 4096 pixels). Textures must be square and use power-of-two dimensions.
• Triangle count is capped — Models cannot exceed 200,000 triangles. Sellers should optimize geometry to stay within this limit while maintaining visual fidelity.
• Alignment determines approval — Improper model alignment or orientation will block or delay publication. Every model must be aligned according to its product type: floor, wall, ceiling, or tabletop.
• PBR materials are required — Amazon uses Physically Based Rendering with the metal/roughness workflow, meaning your materials must be PBR-compliant to render correctly on the platform.

Technical Geometry Requirements

Amazon enforces several geometry rules that 3D artists and sellers must follow carefully. Models must be constructed at real-world scale so that product dimensions are accurate when rendered in the customer experience. The triangle count ceiling of 200,000 ensures models load efficiently across devices. Sellers should also verify mesh integrity before submission — invalid triangles, flipped normals, problematic edges, or degenerate faces can all trigger rejection. Additionally, models must not contain modifiers, animation keyframes, cameras, or lights, as these elements are incompatible with Amazon's rendering pipeline. For eyewear specifically, Amazon requires glTF assets to contain designated node names for virtual try-on compatibility.
