Facebook doesn't publish a pixel size for ordinary posts. The only pixel numbers Meta gives for feed photos are ad minimums: 1440 × 1800 for a 4:5 portrait and 1080 × 1080 for a square. The one hard rule for every photo you post to a Page is a file no bigger than 10 MB.
So the honest answer to "what's the Facebook post size?" is: use Meta's ad minimums as your floor, keep the file under the limit, and ignore anyone who quotes you an "official" organic size. Below is every number Meta actually publishes, where it comes from, and what it means for a wedding gallery. Last checked 25 October 2026.
What size should a Facebook post be?
Post a 4:5 portrait at least 1440 × 1800 pixels, or a square at least 1080 × 1080, as a JPEG under 10 MB. Those are Meta's minimums for Facebook Feed ads, the closest thing it publishes to a size for a feed photo, and the 10 MB file limit applies to every photo posted to a Page.
Meta treats those numbers as a floor, not a target. The same page opens: "It is recommended that you use the highest-resolution images available. These are just the minimum pixel requirements." For an ordinary post, going bigger than Meta's 1440 × 1800 minimum is allowed; Meta just doesn't say what Facebook does with the extra pixels.
| Post | What Meta publishes | Where it says so | What it means for you |
|---|---|---|---|
| Feed photo (ordinary post) | No pixel size. Files up to 10 MB; PNGs under 1 MB "or the image may appear pixelated" | Page photos reference | Post a JPEG, not a PNG |
| Feed photo, portrait (ads) | 4:5, at least 1440 × 1800 | Minimum image sizes for Meta ads | The best published floor for a portrait |
| Feed photo, square (ads) | 1:1, at least 1080 × 1080 | Minimum image sizes for Meta ads | The floor for a square |
| Story | 9:16 recommended; 1080 × 1920 given for Story videos only | Aspect ratio best practices · Page Stories API | No pixel size for a Story photo |
| Link preview (sharing your blog) | At least 1200 × 630, close to 1.91:1, under 8 MB | Images in link shares | Size your blog's sharing image to this |
The two ad rows come from Meta's advertising help centre, not from a page about ordinary posts. They are still the only feed pixel sizes Meta publishes anywhere we could find.

Is there an official Facebook post size for ordinary posts?
No. Meta's documentation for Page photos lists file types and a 10 MB limit, then says only that Facebook "resizes images to different dimensions to best support rendering in multiple sizes".
That's the whole of it. There is no maximum width, no recommended size and no list of the sizes Facebook makes. The pixel figures you'll find on blogs and design-tool size guides for "Facebook post size" don't come from a Meta page about ordinary posts; some are ad specs, and one popular figure is Facebook's size for link previews (below).
A long-edge number for "high quality" uploads also does the rounds in photography groups. We looked for it on Meta's own pages and couldn't find it, so it isn't in this guide.
What aspect ratio is best for photos on Facebook?
Portrait 4:5 is the shape Meta recommends for a single photo in the Facebook feed. Its aspect ratio guidance says "Vertical 4:5 is recommended for single-image ads to be delivered to the ad placement Facebook Feed", and lists 1:1 as the other supported feed shape.
That advice is written for ads, but the reason behind it holds for any post: most people scroll with the phone held upright, and a tall photo fills more of that screen than a square or a landscape does. For a wedding gallery, that means leading with your strongest portrait, not your widest landscape.
Can you post landscape photos on Facebook without cropping?
Meta doesn't publish any shape limit for Page photos, so it doesn't document cropping a landscape at all. What it also doesn't tell you is how large a landscape shows in the feed next to a portrait, so check one on your phone before you post a whole set that way.
A landscape fills less of an upright phone screen than a portrait does. If the photo is about the room, the light or the guests, post it wide. If the couple are small in a big frame, a 4:5 crop from the same photo often does more in the feed.
Does Facebook compress your photos?
Yes: Meta says Facebook "resizes images to different dimensions to best support rendering in multiple sizes". It doesn't publish the quality it re-saves your photo at, so no one outside Meta can give you a real number for it.
Two things you can control, both from the Page photos reference:
- Post JPEGs, not big PNGs. Meta recommends keeping a PNG under 1 MB, "or the image may appear pixelated". A full-size PNG of a wedding photo is many times that.
- Expect your location to go. Facebook "strips all location metadata before publishing", so don't rely on the file to tell people where the wedding was. Put the venue in the caption.
Export in sRGB, the colour space phones and browsers expect, so the colours you edited are the colours people see.
What size is a Facebook Story?
Meta recommends 9:16 for Stories, and gives 1080 × 1920 pixels as the recommended size for Story videos. For a Story photo it publishes only the file rules: under 10 MB, and under 1 MB for a PNG.
The 9:16 advice is on Meta's aspect ratio page ("most people hold their phones vertically"); the 1080 × 1920 figure and the photo file rules are in the Page Stories API documentation. Making a Story photo 1080 × 1920 is a sensible match for the video size, but Meta doesn't state it for photos.
What size is a Facebook link preview image?
At least 1200 × 630 pixels, as close to 1.91:1 as you can, in a file under 8 MB. That's Meta's figure for the image that shows when you share a link, such as your latest wedding blog post, from its link sharing documentation.
The same page says images smaller than 600 × 315 still show, "but the size will be much smaller", and keeping close to 1.91:1 displays "the full image in Feed without any cropping". This is the number most often passed off as the Facebook post size. It isn't; it's the preview for a shared link.
What size is a Facebook post in inches or centimetres?
It has no size in inches or centimetres: Facebook works in pixels, and a screen ignores the DPI setting in your file. Set the pixel dimensions when you export and leave the DPI box alone.
Two exports with the same pixel size look identical on Facebook, whatever DPI each file says. Inches only matter when the photo is printed.
How do you export from Lightroom for Facebook?
Export a JPEG in sRGB, cropped to 4:5, sized 1440 pixels on the short edge so it lands at 1440 × 1800. That meets Meta's portrait minimum and stays well inside the 10 MB limit at normal JPEG quality.
Crop in Lightroom before you export, so you choose the frame and Facebook doesn't have to. If you post the same photo to Instagram, its shape rules are stricter; our Instagram post size guide covers them. Read our full guide to Lightroom export settings for Instagram.
