Article Summary

This guide references the new DSM. Built on customer feedback, the new DSM offers a completely redesigned experience. Learn more about why we made the new DSM.

When building DSM design systems with Sketch, there are some key best practices that will ensure you have the best possible DSM experience. This guide will walk you through:


A good structure for your master Sketch files will greatly improve efficiency in building and using your DSM design system.

File and page setup

Think about your Sketch file architecture as a reflection of your design system structure. We recommend first setting up Foundations and Components as separate Sketch files. There will be portions of your design system that don’t need to exist in Sketch, but it’s best to organize your page structure to match the way you are thinking about grouping Foundations and Components within DSM. This makes the setup process for your design system much faster, and it can help designers quickly find what they're looking for.

For example, if you organize your DSM components like this:

  • Category: Actions
  • Folder: Buttons
  • Page: Primary

Then you might organize your Sketch file like this:

  • Page: Actions
  • Artboard: Buttons
  • Artboard section: Primary
Tip: In both DSM and your Sketch files, you can use emojis to help clarify uses and group like items.

Single file vs connected files

Teams either build a single master Sketch file, or they use a set of linked files as their master.

When supporting a number of products that might need particular parts of a "core" design system but not others (e.g., colors and fonts but not a media card), teams tend to split their files and use shared Sketch libraries to connect. This is also more common for teams that have a number of designers maintaining portions of their master files. By splitting, it's easier to work on the system at the same time.

One thing to be cautious of is making sure all those files are connected and they live in the same place. It’s easy to create a scenario where a designer only has pieces of the Sketch library and is missing critical information.

Working with a single master file typically works well for small teams that need to support a single product. It's easier for small teams to maintain and distribute a single file vs multiple files. However, as the product landscape and teams grow, maintaining a UX library in a single file becomes unruly and calls for switching to a multi-file model.

Here are some reasons for splitting a master file into multiple connected libraries:

  • If there are multiple editors. Splitting the file helps avoid conflicts. One editor can update the icons file, while another updates the components file.
  • If the file size becomes too large. Working and syncing a single file becomes sluggish. Splitting it up into smaller files will speed up your work.
  • If you're supporting multiple products, each with some unique UX elements. To support multiple products, it's easier to maintain a file per product with its unique components and iconography, thus helping reduce "noise." Product-specific files would use shared elements (symbols, styles) from a linked core library. Designers will be able to use elements from the core library, as well as product-unique elements.
  • If you're supporting multiple themes. If you're designing for multiple brands using the same UX elements, but with different styles, you can create a single core library of components—possibly a separate Icons file—and then create a file with styles per theme. This assumes you can meet the theming needs with layer styles and symbols.


Before any of the foundations are built, follow the pages setup instructions and:

  1. Create a foundations Sketch file.
  2. Create a single artboard for colors/layer styles and an artboard for text styles.
    Note: The following sections will cover why you should use a single artboard for colors and layer styles.

Order of operations

When building your master Sketch files from scratch, there is an ideal order of operations. Create your foundations in the following order:

  1. Colors (via color variables and layer styles)
  2. Text styles
  3. Icons

Color variables and layer styles

Following these guidelines when building your files will help you get the most out of color variables and layer stylels in DSM.

Should I use color variables, layer styles, or both?

Colors in Sketch are the most foundational elements and should be the beginning point when creating a system. It's up to you whether you use color variables (introduced in Sketch 69) or layer styles for color fills. In general, layer styles provide a way to apply a collection of properties. Color variables enable you to reuse a single color.

In the Colors category of your design system's Foundations section, you can add colors from color variables or layer style fills. If you do use both, we recommend creating color variables first and applying those variables to the saved layer styles.

What should be included in layer styles?

  • Fills (colors, gradients, photos)
  • Borders
  • Shadows/elevation (inner and outer)
  • Opacity
  • Blurs

Saved layer styles

After a layer style has been created, it’s possible for that style to become unsaved. This essentially means that an update has been made to a one-off use case of that layer style without updating the master layer style (e.g., changing the opacity, updating the hex value from one blue to another, etc.). Any time you see a layer style in the Appearance panel that is italicized with an asterisk, it is unsaved.


There are two main options when a layer style is unsaved:

  • Create a new layer style. Select this option if the change you made to the style is new and will now be reused apart from the original saved layer style.
  • Update the layer style. This option will replace the saved layer style with the changes that have been made in this one-off use case. Note that if you choose to update the existing layer style, it will replace all existing use-cases of this layer style with the new version you’ve created.
If the style is not saved, then users of the library cannot reuse the style. For example, if the one-off change is set on a symbol, when a user of the library uses the symbol via the Sketch library Insert option, they'll get the symbol with its "official" style, not the unsaved one.

Naming conventions

Don’t name your color variables or layers styles by hex value. This is a common mistake that prevents those layers from easily being updated in the future when that hex value is no longer relevant.

Text styles

Text styles allow you to save set text attributes. Once you define a saved text style, it can be reapplied to a number of different components. This reduces errors by having a set of named text styles that are consistent within your design system. It also makes the process of updating or scaling your system much more convenient.

Need to update your H1? Simply update the text style and every component that uses the corresponding style will be updated as well. There's no need to go component by component to make updates, and you can stop worrying if you've caught everything.

What should be included in text styles?

All text in your master Sketch files should be saved. This not only includes headings and paragraphs, but also placeholders, subtitles, footer text, and more.

Here are a few things to include in a text style:

  • Color variables
  • Size
  • Font weight
  • Line height
  • Character, line, and paragraph spacing
  • Alignment
  • Text decoration
  • Text transforms (all caps, all lowercase, or default)
  • Opacity
  • Color

Saved Text Styles

After a text style has been created, it’s possible for that style to become unsaved. This essentially means that an update has been made to a one-off use case of that text style without updating the master text style (e.g., changing the color, alignment, weight, size, etc.). Any time you see a layer style in Sketch's Appearance panel that is italicized with an asterisk, it is unsaved.


Over-engineering text styles

Because Sketch styles require unique saved text styles to account for alignment, color, weight, etc., it’s common to see design systems that account for every possible version of a text style.

Don’t create text styles that aren’t actually used within your system just because you think you might use it in the future. For example, if you never use right-aligned headers, don’t create H1–H6s that are right-aligned. Only create the styles that you'll actually use.


In your Sketch file, save icons as symbols and mark them for export in SVG format. This will allow you to easily add them to your DSM documentation site later.

Icons should be built at set sizes (e.g., 24x24, 48x48) to be available in the override panel for one-off use cases. If icons are built at slightly different sizes, they won’t appear in the Sketch override panel for use.

As with all colors in the Sketch file, icons should use saved layer styles to account for their fills and borders, not just Sketch colors or color swatches.

TipYou can download any icon from the DSM documentation site as an SVG, so consider adding assets as icons that you might frequently download—logos, illustrations, etc.


Order of operations

When building your master Sketch files, build all your foundations first (layer styles, text styles, and icons) in a separate file. Once those have been built, use them to fill out your smallest atomic components, the elements that exist on their own or inside larger components. For example, build your buttons before you build a card that will contain a button.

Anatomy of a component

When building components, follow these guidelines:

  • Apply saved layer styles for all colors that exist within the components.
  • Apply saved text styles for all text that exists within the components.
  • Leverage Smart Layouts for all components that should be responsive.
  • Rename each layer and group within the symbol for ease of use in the override panel. For example: “Background Fill," “Title Text,” or “Image.”
  • Save all components as symbols.
  • Manage overrides in the master symbol that designers shouldn’t be able to adjust.

States and variants

When it comes to states or variants, there are many ways to approach building a component in Sketch.

For components that have designated states—like buttons or input fields—we recommend building unique saved symbols for each state rather than using overrides to account for states

We recommend this approach because:

  • The states and variants are then accessible through Sketch libraries.
  • If you need to change details of a specific state in the future (e.g., updating your primary button hover), you can do so efficiently, knowing that everywhere that state is used, it will be updated.
  • It speeds up delivery time for designers. They no longer have to pull down a master symbol and update layer and text styles to account for a specific state.
  • It maintains consistency in the system and ensures designers are using a component state properly. When using a single master with overrides, it’s easier for designers to inaccurately build a component’s state or to apply styles they aren’t supposed to use.
  • It makes it easier for developers to understand what component state is used in screen design. The symbol name will appear in Inspect when developers inspect a design to build.
The downside of this approach is that editors of the system will need to update all symbols if a property that's shared across all component states changes. For example, if the border radius of the button changes, you'll need to update all button symbols instead of just one.
