Zeplin generates asset formats and scales based on your project type and density. When creating a new project, you can choose the project type and density that fits your needs.
It even has extensions to export code snippets in CSS, HTML, React Native, and other languages. The developers on teams I work with have told me how much time Zeplin saves them. Using Zeplin means they don’t have to hunt for the correct Sketch file. They don’t have to wait for Sketch to open. For iOS and Android projects, Zeplin can generate React Native code snippets. You can enable it for each project separately from the styleguide. You can find more details about features and resources based on project types here: Developing iOS projects using Zeplin. Zeplin also helps the team collaborate by providing much needed organization and structure to native design files. Zeplin provides an inclusive workspace where team members from varying disciplines like product managers, UX writers and more can come together to deliver on designs. Katherine Lee, UX Visual Design Manager. This is a framework which converts Zeplin designs (json schema) to React Native Code snippets - sivarajng/zeplin-to-react-native.
Project type
Zeplin supports four project types; iOS, Android, Web and macOS. When exporting designs to a project, all resources (including measurements, assets and code snippets) are generated automatically based on its project type.
☝️ Since resources are generated during the export process, it's sadly not possible to change the project type after it’s been selected. If you need to change a project’s type, you will need to create a brand new project.
Here are some key differences among project types:
Measurements are in points on iOS projects while they're in dp/sp on Android projects.
Assets are downloadable as PNGand SVG on Android projects and PNG,SVG, and PDF on iOS projects.
For iOS and Android projects, Zeplin can generate React Native code snippets. You can enable it for each project separately from the styleguide.

Project density
Zeplin supports the following densities:
iOS: 1x, 2x, 3x
Android: mdpi, hdpi, xhdpi, xxhdpi, xxxhdpi
Web: 1x, 2x
macOS: 1x, 2x
When exporting designs to a project, Zeplin calculates and displays the correct measurements to developers based on this density setting. Zeplin normally determines the correct density based on the size of your designs, but in some cases, you may be prompted to set it manually.
Your project density depends on the project type (target platform/device) you're working on and the original dimensions of your design. For example, if you're working on 750px × 1136px iOS screen, you will need to select '2x' as your project density. After that, if a measurement is 20px in your original design file, Zeplin will display it as 10pt to help developers out since they use '1x' values while coding.
To select or change the project density, click on the small pencil icon next to the project type and density in the project Dashboard.

☝️ The density only needs to be selected once by the designer(s), but they can change the project density anytime.
When selecting a density from the selection window, a list of commonly used artboard sizes is shown next to each density. You can use this as a reference for deciding which density to select.
