Design Sizes & Dimensions Reference

Getting the dimensions right before you start designing saves you from resizing (and re-laying-out) after the fact. This page is a reference table for the most common formats you'll set as a frame size in Lega — social posts, stories, ads, print pieces, and web assets — so you can look up a size once and move on.

Each frame in Lega is an independent artboard with its own dimensions; see Frames & Artboards for how to create and resize them. Once your design is ready, Exporting Your Design covers formats and resolution.

Social media sizes

These platforms update their preferred dimensions periodically, and cropping behavior varies by placement (a feed post displays differently than the same asset in a story). For the higher-detail, more frequently refreshed version of this table — including safe zones and platform-specific gotchas — see the companion post: Social Media Sizes Cheat Sheet.

Print sizes

Print dimensions are conventionally specified in inches, not pixels, because the final output is physical. At a standard 300 DPI (dots per inch) for print-quality resolution, here's how common sizes translate:

These figures are for the trim size — the final cut size of the piece. Print jobs typically need extra bleed area added around the edges, and color and resolution requirements of their own; the full rundown is in the Print-Ready Export Checklist — don't export a print job straight off this table without reading it first.

Web sizes

Web assets are generally lower-stakes on resolution than print — screens render at a fixed pixel density, so there's no equivalent of a DPI requirement. What matters more is matching the exact placement dimensions so the asset isn't stretched or cropped unexpectedly by the platform.

Setting a custom frame size

Every size above is a starting point, not a constraint — Lega frames accept any custom width and height. If you're designing for a format not listed here (a non-standard ad unit, an unusual print piece, a specific screen size), set the frame's dimensions directly when creating it. See Frames & Artboards for the mechanics of creating and resizing frames, including how multiple frames of different sizes can coexist in a single document — useful when you're producing a matched set of assets (a post plus its story variant, say) in one session.

A note on aspect ratio vs. exact pixels

When a platform's own guidance gives a range rather than an exact number, matching the aspect ratio matters more than hitting the exact pixel count — platforms resample images to their internal size anyway. Where this table gives one canonical number per format, it's the safest choice: large enough to avoid upscaling, and aligned to what the platform expects.

If you're unsure which size to reach for, Exporting Your Design has guidance on choosing resolution multipliers relative to a frame's base size, which pairs with the dimensions here to get you a final file suited to wherever it's headed.
