shadcn/ui Component Statistics 2026: 62 Analyzed

1. The median shadcn/ui component is 97 lines of source code, measured across 62 components in the base-vega style; together they come to 8,575 lines.

   Denominator: all 62 analyzed components. Link to this finding

2. Sidebar is the largest shadcn/ui component at 730 lines, followed by Chart (372) and Questionnaire (332). 17 of the 62 components (27%) are 200 lines or longer.

3. 15 of the 62 shadcn/ui components (24%) define style variants with class-variance-authority (cva); the other 47 have no cva variants.

4. 22 of the 62 shadcn/ui components (35%) install at least one other shadcn/ui component as a registry dependency; the other 40 stand alone.

5. Button is the most reused building block: 14 of the 62 components (23%) depend on it, followed by Separator (4).

   Denominator: all 62 analyzed components. A component counts once per dependency it lists. Link to this finding

6. The median shadcn/ui component exports 4.5 parts; 13 of the 62 components (21%) export a single part and 12 (19%) export 10 or more.

   Denominator: all 62 analyzed components. A part is an exported function component. Link to this finding

7. Components that build on other shadcn/ui components are larger: a median of 208.5 lines for the 22 that do, against 67.5 for the 40 that stand alone.

   Two groups: 22 components with registry dependencies and 40 without. Differences under 10% are reported as about the same. Link to this finding

• Source: the shadcn/ui registry index (https://ui.shadcn.com/r/index.json). Every item of type registry:ui, 65 in total, was fetched from https://ui.shadcn.com/r/styles/base-vega/<name>.json on October 26, 2026.
• Included: 62 of the 65 items. Excluded: Direction, because its source exports no function components the parser can read (a re-export or an arrow-function wrapper); Form, because it ships no source code in this style; Sonner, because its source exports no function components the parser can read (a re-export or an arrow-function wrapper).
• Lines: every line of the item's published files joined together, trailing blank lines removed. Comments and blank lines inside the file count.
• Parts: exported functions whose names start with a capital letter. Components written as arrow functions are not counted.
• cva variant groups: keys of the variants object in each cva() call. Registry dependencies: the item's registryDependencies list.
• Not reported: npm dependencies, because the base-vega style declares shared packages such as @base-ui/react once for the whole style rather than on every item.
• One style only: the base-vega style, which is built on Base UI. Radix-based styles may differ in size.
• Every value is computed from published code; none is entered by hand or by users.
• Refreshed when the snapshot is re-fetched with pnpm shadcn:snapshot. The date on this page is the fetch date.
• Percentages are rounded to the nearest whole number, so a table can add up to 99% or 101%. A median of an even count is the mean of the middle two values.
• A finding that compares two groups needs at least 20 components in each group.
