Use CSS Grid when items need to line up in shared rows and columns. Use Flexbox when items should flow along one axis and size or distribute themselves according to their content. A wrapped Flexbox layout is not inherently wrong; it becomes the wrong tool when you have to tune item widths to make separate rows align.
First decide what needs to align
Ask whether the layout needs control along one axis or across rows and columns. If each row can size its items independently, Flexbox may be a good fit. If items in later rows must sit on the same column tracks as items above them, Grid expresses that requirement directly.
MDN puts the distinction this way: “As a general rule, if you are setting widths on flex items to make items in one row of a wrapped flex container line up with the items above them, you should instead opt for a two-dimensional grid layout.” MDN’s Flexbox and Grid guide explains why: each wrapped flex line distributes space independently rather than aligning its items to items on other lines.
Why wrapped Flexbox does not make a true grid
Flexbox lays out items along one main axis at a time: a row or a column. With wrapping enabled, it creates multiple flex lines, but those lines are not a shared set of columns. An item’s size and the available space on its own line determine the distribution there; the next line does not inherit column boundaries from the one above.
This is useful when the content should drive the flow, such as controls that wrap when space gets tight. It is awkward when you compensate for the lack of shared tracks by assigning widths or bases until the rows happen to line up. That approach makes the layout logic harder to understand and maintain because you are manually approximating a two-dimensional structure.
What Grid gives you instead
CSS Grid defines rows and columns as tracks, then places items into that two-dimensional structure. Items in different rows can share column tracks; you can also control placement, span items across tracks, and, where needed, deliberately overlap items. Grid can place items automatically into tracks or let you explicitly position them. See MDN’s Grid basics and its guide to Grid and other layout methods.
A responsive card collection
For a card collection whose columns should remain aligned as the number of cards changes, a flexible-track pattern could look like this:

display: grid;
grid-template-columns: repeat(auto-fit, minmax(200px, 1fr));
gap: 1rem;
}auto-fit lets Grid fit as many columns as the available width allows, while minmax() sets a lower bound and permits tracks to grow. Here, 200px is an illustrative minimum, not a universal setting: choose a value that keeps the actual card content usable at the available widths. MDN demonstrates this approach in its Grid and other layout methods guide.

When Flexbox is still the right choice
Use Flexbox when the job is to arrange and distribute content along a single axis, with the items’ own sizes influencing the result. A toolbar is a typical example: buttons and controls can sit in a row and wrap according to their content and available space. If the items do not need to share column alignment across multiple rows, wrapping Flexbox is a valid layout.
There is no rule that a small component must use Flexbox or that a large layout must use Grid. The deciding factor is the layout relationship you need, not the component’s size. MDN notes that either method can work in some cases; choose according to the structure and behavior the design requires.
Choose by the container’s job
| Layout requirement | Better starting point | Why |
|---|---|---|
| Arrange items in one row or column; let their content influence sizing and distribution | Flexbox | It is a one-dimensional layout model. |
| Keep columns aligned across multiple rows | Grid | Shared tracks coordinate both dimensions. |
| Wrap independent controls when they run out of room | Flexbox | Each line can flow and distribute items independently. |
| Define tracks, span items, or deliberately place items in two dimensions | Grid | Track-based placement makes those relationships explicit. |
| Build a page or card collection with components that also need internal rows or columns | Use both where appropriate | Grid and Flexbox are complementary; each container can use the model that fits its own job. |
Use Grid and Flexbox together
These are complementary tools, not competing site-wide choices. Grid can define the outer page or a card collection, while Flexbox arranges the contents inside a card or toolbar. The CSS Working Group’s Grid Level 2 editor’s draft describes Grid as a two-dimensional layout system and notes the distinct, complementary strengths of Grid and Flexbox. It is a draft rather than a final specification; MDN’s guides are the practical references for the examples above.
