Snapchat public profile header size
Short answer
Snapchat Business publishes both numbers for a public profile header: upload at 375 x 569 px and expect 375 x 258 px to be visible. That is 311 px of the 569 px height not shown, which is 54.7%. Keep anything readable inside the visible band.
Key takeaways
- Snapchat Business states an upload size of 375 x 569 px and a visible size of 375 x 258 px on the profile.
- 311 px of the 569 px height is not shown, which is 54.7% (computed: 1 − 258 / 569).
- The upload file must be under 2 MB when set through Ads Manager on the web.
- Snapchat does not say whether the crop comes off the top, the bottom or both, so design so the middle 258 px works alone.
- This is the one Snapchat figure in the block that came from Snapchat: the consumer help pages we fetched on 2026-10-07 all returned 404s.

Resize it now
375 x 569 px, the upload size in the Snapchat Business article. The tool center-crops into that tall frame, and only the middle 375 x 258 px survives the visible crop, so anything readable has to be in that band.
Batch is unlimited and free - every image is processed on your device, so there is no queue and no daily cap.
The only Snapchat size we could read from Snapchat
Snapchat's Business Help Center article "Set Up a Header Image" is the only Snapchat image page that returned real content on 2026-10-07. The consumer help center returned 404s, which is why the consumer avatar carries third-party figures instead.
The article states the dimensions as a pair, which is unusually useful: upload at 375 x 569 px, and 375 x 258 px is visible on the profile. Most platforms publish one number and crop the rest to taste. Snapchat publishes both, so the crop is knowable rather than inferred.
It also gives a file constraint of under 2 MB, stated for the web upload path, and both routes for setting it, which differ: on mobile you pick from the camera roll in profile management, and on the web you upload under Profile Details, then Hero Image, then Save, then Update Profile.

The crop, and the one thing Snapchat does not say
The upload is 569 px tall and the visible band is 258 px, so 311 px is not shown. What Snapchat does not state is where those 311 px come from: the top, the bottom, or a split.
Computed as an even split, 311 / 2 = 155.5 px off the top and 155.5 px off the bottom, leaving 258 px visible, which is 45.3% of the upload. The split is arithmetic, not a published crop map, and this page says so rather than implying Snapchat described it.
The design rule that does not depend on knowing the split: make the middle 258 px work alone. If the header needs a headline, put it in that band and treat the rest as imagery.
The two shapes are very different, which is the whole problem
The upload is 0.659:1 and the visible band is 1.453:1. Those are not variations on one shape; they are a portrait frame and a landscape window, which is why a header designed as a wide strip and uploaded into a tall frame looks wrong.
Computed: 375 / 569 = 0.659 and 375 / 258 = 1.453. An image that fills the upload edge to edge loses its sides when the visible band is taken from the middle, so keep essential content within the band's width as well as its height.
The measured run on this page puts 375 x 569 px at 38 kB as JPEG and 15 kB as WebP, against a 2 MB cap, so the file constraint is not what shapes the design. The visible band is.
How it differs from a consumer Snapchat avatar
The header is one element of a Snapchat Business public profile, and it sits above a profile image whose size we could not confirm: the three consumer help pages we fetched on 2026-10-07 returned 404s. Sprout Social lists a Snapchat profile picture at 320 x 320 px and the same header at 375 x 569 px, and Canva lists the header too, which is independent agreement on the header figure.
The separation is worth keeping clear: this page is the one in the batch where the figure is Snapchat's own, and the consumer avatar is not. A 375 x 569 px header is not a substitute for a square avatar, and uploading one as the other produces the small-square-in-a-tall-frame result shown in the fit table above.
- Upload 375 x 569 px, which is the published size.
- Keep text inside the central 375 x 258 px band.
- Stay under 2 MB on the web path.
- On mobile, the cover is set from the camera roll in profile management, with no crop guidance published.
- Check the result on a phone, because the header is most often seen there.
Frequently asked questions
What size is a Snapchat public profile header?
375 x 569 px to upload, of which 375 x 258 px is visible on the profile. Snapchat Business publishes both figures, and the file must be under 2 MB on the web upload path.
How much of a Snapchat header is cropped?
311 px of the 569 px height, which is 54.7%, computed as 1 − 258 / 569. Snapchat does not say whether the crop comes off the top, the bottom or both, so design so the middle 258 px works on its own.
How do I change a Snapchat Business profile header?
On mobile, open Profile Management, select the public profile, tap the icon next to Add a Cover Photo and save. On the web, use Ads Manager, Public Profiles, Profile Details, Hero Image, then Save and Update Profile.
What is the maximum file size for a Snapchat header?
Snapchat Business states under 2 MB for the web upload through Ads Manager. At 375 x 569 px you are far below that for any normal image: the measured run on this page produced 38 kB as JPEG.
Is this the same as a Snapchat profile picture?
They are different assets with different confidence behind them. The header at 375 x 569 px, showing 375 x 258 px, comes from Snapchat Business Help. The personal avatar is not covered by that article, and the three consumer pages we fetched returned 404s, so the 320 x 320 px you see elsewhere is a publisher figure.
