Look up a placement to get its frame dimensions and aspect ratio before you crop.

Output sizes do not guarantee sharpness — encode at the source resolution the platform accepts and let it downscale.

Choose a frame before cropping

These three placements use different shapes. A square post and a vertical story both start at 1,080 pixels wide, while a video thumbnail uses a wider frame.

How to choose a frame from the size reference

  1. Find the placement

    Start with where the asset will appear, such as a vertical Story or a link preview.

  2. Read pixels and ratio together

    Pixels give the export dimensions. The ratio tells you how tightly the original shot will crop.

  3. Check the subject at that size

    Keep essential details inside the intended frame, then preview it in the destination app.

Plan the crop before the shoot

Use the aspect ratio to decide how much space to leave around subjects and text.

Frame a vertical Reel

Keep the main action near the centre when you may also need a square crop.

Plan a feed image

Compare portrait and square framing before you place product copy near the edges.

Brief a thumbnail

Leave space for the title within a landscape frame when composing the still.

Prepare a link card

Choose the wide share-image shape before arranging a headline and product photo.

Social image and video sizes FAQ

Do 4:5 and 9:16 show the same part of my photo?

They are different portrait shapes. A 9:16 frame is narrower for the same height, so allow more room at the sides of the subject when planning both crops.

What is the difference between size and ratio?

Size is measured in pixels. A ratio describes the shape, so multiple pixel sizes can share the same framing.

Will this change my file?

The table is a reference. Use the image resizer or video cropper to produce an actual new file.

How should I use the placement notes?

Treat them as starting points for composition. Preview the result on the target device, especially when text sits near player controls.

Which dimensions should I start with for a vertical Story?

Use the 1080 × 1920 row. That 9:16 frame is taller than the 1080 × 1350 portrait feed crop, so check the composition separately.

Which size in the table fits a link preview?

The Open Graph row gives 1200 × 630. Use that canvas when preparing a wide image for a shared page link.

Do I need a new export if the pixel size changes but the ratio stays the same?

If the destination requires specific pixel dimensions, export at that size. A 540 × 960 image has the same 9:16 proportions as 1080 × 1920 but contains fewer pixels.
