Banner ad sizes 2026: Google Display and social media ad specs

If you make only one display banner, make it 300 × 250 px, the medium rectangle. It sits in or beside the page content, and Google lists it among the most common sizes. Add 728 × 90 for the top of desktop pages and 320 × 50 for phones. For social ads, make one vertical 9:16 version for Stories, Reels, TikTok and Snapchat, and one 4:5 version for feeds.

Find your placement in the table below, then go to the platform's section for minimums, file limits and text limits. We checked these specs against each platform's own help pages in October 2026. Platforms change them often, so look at the upload screen before a big launch.

Google Display Network banner sizes

Google's display ads use the standard banner sizes set by the Interactive Advertising Bureau (IAB), so the same files work on other ad networks that use IAB sizes. The first four rows are the sizes to make first.

Size	Name	Where it usually shows
300 × 250 px	Medium rectangle (Google calls it inline rectangle)	In or beside the content
728 × 90 px	Leaderboard	Across the top of a desktop page
320 × 50 px	Mobile banner (also called mobile leaderboard)	Top or bottom of a phone screen
300 × 600 px	Half-page ad	Sidebar
160 × 600 px	Wide skyscraper	Sidebar
970 × 250 px	Billboard	Top of the page, for brand campaigns
970 × 90 px	Large leaderboard	Across the top of a wide desktop page
336 × 280 px	Large rectangle	In or beside the content
320 × 100 px	Large mobile banner	Phone screens, twice the height of 320 × 50
300 × 50 px	Mobile banner	Phone screens, a little narrower than 320 × 50
468 × 60 px	Banner	Older site layouts

Image ads take JPG, PNG or GIF files up to 150 KB. HTML5 ads are a ZIP file up to 600 KB, but Google offers them only to accounts that have been open more than 90 days, have spent more than $9,000 in total and have a good policy record.

Responsive display ads: Upload images, Google fits them

Responsive display ads are Google's default ad type for the Display Network. You upload images and text, and Google builds an ad for each placement, so you don't make every banner size by hand. The trade-off is that you control less of the final look than with a fixed banner.

Image	Recommended	Minimum
Landscape, 1.91:1 (at least one)	1200 × 628 px	600 × 314 px
Square, 1:1 (at least one)	1200 × 1200 px	300 × 300 px
Vertical, 9:16 (optional)	900 × 1600 px	600 × 1067 px

Each image can be up to 5,120 KB. Logos come in two shapes: square at 1200 × 1200 px (128 × 128 px at least) and landscape 4:1 at 1200 × 300 px (512 × 128 px at least).

Social media ad sizes

Each social platform sets its own specs. Stories, Reels, TikTok and Snapchat are built for full-screen vertical 9:16, while feeds take 4:5, square or landscape.

Facebook and Instagram (Meta)

Facebook and Instagram ads share most specs, so one set of files serves both. Meta now recommends 4:5 for feeds and larger images than the 1080 px sizes many older guides list.

Placement	Size	Ratio
Feed, image or video	1440 × 1800 px recommended	4:5 (1:1 also works)
Stories and Reels, image or video	1440 × 2560 px recommended	9:16
Carousel, Facebook feed	At least 1080 × 1080 px	1:1
Carousel, Instagram feed	At least 1080 × 1080 px	4:5 when every card is an image; 1:1 when a card is a video

Images are JPG or PNG, up to 30 MB. Videos are MP4 or MOV, up to 4 GB. A feed video can run from 1 second to 241 minutes, a Reels video up to 15 minutes and an Instagram Stories video up to 60 minutes. A carousel has 2 to 10 cards. Your file may be off the exact ratio by up to 3% in the Facebook feed and 1% on Instagram.

In Stories and Reels, the profile name and buttons cover the edges of the screen. Meta advises keeping text and logos out of roughly the top 14%, the bottom 35% and 6% on each side.

Text limits depend on the placement:

Placement	Primary text	Headline
Facebook feed	50 to 150 characters	27 characters
Facebook feed carousel	80 characters	20 characters, plus an 18-character description
Instagram feed	125 characters, up to 30 hashtags	40 characters

These limits come from Meta's ads guide for awareness campaigns; other campaign objectives can differ slightly.

TikTok

TikTok in-feed ads are video. Vertical 9:16 is recommended; square and horizontal videos are accepted.

Ratio	Minimum size
Vertical, 9:16 (recommended)	540 × 960 px
Square, 1:1	640 × 640 px
Horizontal, 16:9	960 × 540 px

Files can be MP4, MOV, MPEG, 3GP or AVI, up to 500 MB, with a bitrate of at least 516 kbps (kilobits per second). In-feed videos can run up to 10 minutes. Spark Ads, made from existing TikTok posts, have no length limit.

TopView, a placement you book in advance, is stricter: vertical 9:16 only, at least 540 × 960 px, 5 to 60 seconds (9 to 15 recommended), at least 2,500 kbps and up to 500 MB.

X (Twitter)

Format	Size
Image ad	1:1 (1080 × 1080 px) or 1.91:1 (2064 × 1080 px); X recommends at least 800 × 800 px or 800 × 418 px. It also accepts 16:9 (1920 × 1080 px), 9:16 (1080 × 1920 px), 4:5 (1440 × 1800 px) and 2:3 (1080 × 1620 px).
Video ad	1920 × 1080 px (16:9) or 1200 × 1200 px (1:1) recommended; vertical 9:16 also runs

Images are PNG or JPEG, up to 5 MB. Videos are MP4 or MOV, up to 1 GB. X recommends videos under 15 seconds and supports up to 2 minutes 20 seconds.

LinkedIn

Single image ads come in three shapes. Vertical images show on mobile only. LinkedIn still accepts the older 628 × 1200 px vertical but adds borders to it, so use 4:5.

Single image ad	Recommended	Minimum	Maximum
Horizontal, 1.91:1	1200 × 628 px	640 × 360 px	7680 × 4320 px
Square, 1:1	1200 × 1200 px	360 × 360 px	4320 × 4320 px
Vertical, 4:5 (mobile only)	720 × 900 px	360 × 640 px	2430 × 4320 px

Images are JPG, PNG or GIF (animated GIFs up to 250 frames), up to 5 MB.

Video ad	Recommended	Minimum	Maximum
Horizontal, 16:9	1920 × 1080 px	640 × 360 px	1920 × 1080 px
Square, 1:1	Any size in range	360 × 360 px	1920 × 1920 px
Vertical, 4:5 (recommended)	720 × 900 px	360 × 450 px	1080 × 1350 px
Vertical, 9:16	720 × 1280 px	360 × 640 px	1080 × 1920 px

Videos are MP4, 75 KB to 500 MB, and 3 seconds to 30 minutes long. LinkedIn recommends 15 to 30 seconds. An optional thumbnail is JPG or PNG, up to 2 MB, in the same ratio as the video.

Text in image and video ads	Recommended	Maximum
Introductory text	150 characters	3,000 characters
Headline	70 characters	200 characters
Description (image ads)	100 characters	300 characters

Two other LinkedIn formats have their own specs:

• Carousel ads: 2 to 10 square cards, 1080 × 1080 px recommended, up to 4320 × 4320 px and 10 MB per card, in JPG, PNG or non-animated GIF. Carousels take no video. Introductory text: 150 characters recommended, 255 at most.
• Message ads: a banner of up to 300 × 250 px that shows on desktop only, in JPG, PNG or non-animated GIF, up to 2 MB. The message holds up to 1,500 characters. In the EEA and Switzerland, only members who opted in receive these ads.

YouTube

Video shape	Recommended	Minimum
Horizontal, 16:9	1920 × 1080 px	1280 × 720 px
Vertical, 9:16	1080 × 1920 px	720 × 1280 px
Square, 1:1	1080 × 1080 px	480 × 480 px

YouTube also accepts 4:5 for vertical video. Files can be up to 256 GB. MPG (MPEG-2 or MPEG-4) is recommended, and MP4, MOV, AVI, WMV and other common formats work too. Google's specs list 15 seconds for skippable in-stream and in-feed ads, 6 seconds for bumper ads and 6 to 60 seconds for Shorts.

On desktop, a video ad can come with a companion banner: 300 × 60 px, in JPG, GIF or PNG, under 150 KB.

Snapchat

Every Snapchat ad format fills the phone screen at 9:16: single image or video ads, Story ads, Collection ads and Commercials. Use 1080 × 1920 px; 720 × 1280 px is the minimum.

Images are JPG or PNG, up to 5 MB. Videos are MP4 or MOV, 3 to 180 seconds long. Commercials are video only, and people can't skip their first 6 seconds.

Which sizes to make first

Start with the sizes that run in the most places, then add the rest as your budget allows:

1. 300 × 250 for the web. It runs on desktop and mobile pages.
2. 728 × 90 and 300 × 600 (or 160 × 600) for desktop.
3. 320 × 50 for phones, plus 320 × 100 where a taller banner fits.
4. A 970 × 250 billboard for a brand campaign.
5. For social, one 9:16 version of at least 1080 × 1920 for Stories, Reels, TikTok and Snapchat, and one 4:5 version at 1440 × 1800 for Facebook, Instagram and LinkedIn feeds.

If you run responsive display ads on Google, upload the landscape and square images and let Google fill the other placements.

Checks before you upload

A banner at the right size can still be rejected or look wrong. Check these before each upload:

• The file matches the placement's ratio, not just roughly its size.
• The file type is accepted and under the limit, such as 150 KB for Google image ads.
• The text is readable at the real size. A small banner takes a few words, not a paragraph.
• In 9:16 ads, text and logos stay clear of the edges, where buttons and the profile name sit.
• Every size carries one message and the same branding.
• You have phone sizes and vertical versions, not only desktop banners.
• You run more than one size and compare results before you put more budget behind one.
