DV360 Ad Specs: DV360 Ad Sizes, Display Ad Specs and Creative Requirements
Display and Video 360 is where enterprise and agency teams buy programmatic display, and it is also where a creative brief quietly turns into twenty one export jobs. The specs themselves are not complicated, but they are scattered across several Google help pages, they differ from Campaign Manager 360 by just enough to cause trafficking failures, and the Demand Gen inventory that now sits in the same platform runs on an entirely different sheet. This page pulls the current numbers into one place, sourced from Google's own documentation rather than from other agency blog posts, and marks where the platforms disagree. Everything below is the display side: image and HTML5 creative rules, the full supported size table, and the character limits on optimized creatives. Build a set at the top of the page if you want the standard banner sizes produced from a product URL before you read the table.

Direct answer
DV360 ad specs fall into three groups. Image creatives accept JPG, GIF and PNG files up to 4000 x 4000 pixels and 10 MB. HTML5 creatives upload as a ZIP of up to 100 files with no cap on the ZIP itself, but Display and Video 360 limits the total file size a browser downloads when the ad serves to 5 MB. Optimized creatives, the responsive format, take up to five short headlines of 30 characters, one long headline of 90 characters, up to five body blocks of 90 characters, a 25 character advertiser name and a 15 character call to action, with images capped at 2000 x 2000 pixels and 1200 KB. Google documents roughly twenty supported display dimensions across square, skyscraper, leaderboard and mobile families, of which 300 x 250, 728 x 90, 160 x 600, 300 x 600 and 320 x 50 carry most inventory.
The problem
The specs are the easy part. The expensive part is what they imply. A single display concept has to exist as a medium rectangle, a leaderboard, a wide skyscraper, a half page and at least two mobile banners before it can compete for a reasonable share of inventory, and each of those is a different crop, a different type size and a different decision about how much copy survives. At 320 x 50 there is room for a logo and roughly four words. At 300 x 600 the same message has to fill vertical space without looking padded. That is not one design job repeated seven times, it is one design job and six re-layouts, and it is the reason display campaigns so often launch with two sizes and a plan to add the rest later that nobody gets to. The knock on effects are familiar to anyone who has run a programmatic line item: delivery caps out because the buy can only fill a fraction of matched inventory, frequency climbs on the sizes that do exist, and creative refresh slips from monthly to whenever someone has a free afternoon. None of that shows up as a creative problem in reporting. It shows up as underdelivery and rising CPMs.
How Adscreator handles it
Adscreator handles the image creative half of a DV360 buy. Give it a product URL or a description of the offer and it writes headline and body options that fit the character limits above, generates on brand imagery from your colors, logo and fonts, and renders the standard display dimensions in one pass, so the seven sizes that matter come back as a set rather than as a week of exports. Because it returns variants instead of one execution, the creative refresh that usually stalls stays cheap enough to actually do. Be clear about the boundary before you plan around it. Adscreator produces static image creatives and ad copy. It does not build or export HTML5 ZIP packages, it does not produce video, CTV or audio creative for the other DV360 formats, it does not traffic or serve ads, and it has no connection to your DV360 seat, so finished files are uploaded to the platform the same way any image creative is. For the image line items in a display buy, that covers the work. For rich media and video, you still need a production partner or an HTML5 build tool. The product is not open for purchase yet. Planned pricing starts at $39 monthly, flat, and you can join the waitlist from the panel above.
specs
Every display ad size Display and Video 360 documents as commonly supported.
These are the dimensions Google lists in its own image creative guidelines, grouped the way Google groups them. Two caveats matter before you build against the table. Other sizes can and do serve, because supported dimensions vary by site, app and region, so this is the common set rather than a closed list. And inventory is heavily concentrated: a handful of these units carry most of the impressions available on a typical US buy, which is why the notes column flags what is worth producing first.

| Size in pixels | Common name | Family | Notes for a US display buy |
|---|---|---|---|
| 300 x 250 | Medium rectangle | Square and rectangle | The highest volume unit in programmatic display. Build this one first. |
| 250 x 250 | Square | Square and rectangle | Fills small in article slots that reject 300 x 250. |
| 320 x 320 | Large square | Square and rectangle | Mobile web in feed placements. |
| 336 x 280 | Large rectangle | Square and rectangle | Slightly larger sibling of 300 x 250, common in article bodies. |
| 120 x 600 | Skyscraper | Skyscraper | Legacy sidebar unit, still requested by some publishers. |
| 160 x 600 | Wide skyscraper | Skyscraper | The sidebar unit worth building. Outsells 120 x 600 by a wide margin. |
| 300 x 600 | Half page | Skyscraper | High viewability and strong CPMs. Second priority after 300 x 250. |
| 300 x 1050 | Portrait | Skyscraper | Premium desktop takeover style slot, limited inventory. |
| 468 x 60 | Banner | Leaderboard | Old standard, thin inventory now. Skip unless a publisher asks. |
| 728 x 90 | Leaderboard | Leaderboard | Core desktop unit. Build alongside 300 x 250 and 160 x 600. |
| 800 x 250 | Billboard variant | Leaderboard | Wide desktop slot, narrower inventory than 970 x 250. |
| 970 x 90 | Large leaderboard | Leaderboard | Desktop above the fold on wide layouts. |
| 970 x 250 | Billboard | Leaderboard | Premium desktop unit with strong viewability. |
| 300 x 50 | Mobile banner | Mobile | Smallest mobile unit. Room for a logo and about four words. |
| 300 x 100 | Large mobile banner | Mobile | Slightly taller mobile slot with room for a call to action. |
| 320 x 50 | Mobile leaderboard | Mobile | The dominant mobile web banner. Build it. |
| 320 x 100 | Large mobile leaderboard | Mobile | Better performing mobile unit where inventory allows. |
| 320 x 480 | Mobile interstitial | Mobile | Full screen app and mobile web interstitial. |
| 360 x 592 | Mobile interstitial | Mobile | Taller interstitial for modern handset aspect ratios. |
| 360 x 640 | Mobile interstitial | Mobile | Common Android interstitial dimension. |
| 375 x 667 | Mobile interstitial | Mobile | Interstitial sized to older iPhone viewports. |
Sizes are taken from the Display and Video 360 image creative guidelines. The priority notes are our own read of where US programmatic inventory concentrates, not Google's guidance, and the correct way to settle it for your own account is an Inventory Availability report run against your actual targeting, which returns the dimensions of inventory you could be buying rather than a generic list. Image creatives across all of these sizes accept JPG, GIF and PNG up to 10 MB, though publisher specifications frequently require far less.
The file size limit everyone quotes is the wrong one
There are three different size ceilings in Display and Video 360 and they get conflated constantly in agency spec sheets. The first is the image creative limit: 10 MB at up to 4000 x 4000 pixels. The second belongs to Campaign Manager 360, which documents 9.5 MB for display creative image assets, half a megabyte lower than its sibling platform. The third, and the only one that affects delivery, is the HTML5 rule: DV360 places no cap on the ZIP you upload, which can hold up to 100 files, but it limits the total file size a person's browser downloads when the ad actually serves to 5 MB. Teams read the 10 MB figure, build a heavy HTML5 unit, and then cannot work out why it fails validation or underdelivers. Two practical rules follow. If you are producing one asset library that will be trafficked through both DV360 and Campaign Manager 360, size to 9.5 MB so the same files clear both. And treat 5 MB as the number that governs anything interactive, while aiming far below it, because publisher specifications routinely require smaller payloads than Google's ceiling and a banner competing in an auction is competing on load time too.
Build seven sizes, not twenty one
Google lists roughly twenty commonly supported display dimensions, and the instinct on seeing that table is to produce all of them. That is how a single campaign turns into three weeks of export work. Inventory is not distributed evenly across those sizes, and a small subset carries the overwhelming majority of programmatic impressions. For most US display buys, 300 x 250, 728 x 90, 160 x 600, 300 x 600 and 320 x 50 will reach the bulk of available inventory, with 970 x 250 and 320 x 100 worth adding for premium desktop and better performing mobile placements. Everything else is worth building when a publisher asks for it, a specific deal ID requires it, or your own delivery reports show inventory you are failing to fill. The right method is to check rather than guess: DV360 lets you run an Inventory Availability report against your actual targeting, which returns the dimensions of the inventory you could be buying. Build against that report and you will usually find seven sizes covers what twenty one was meant to. The saving is not just design hours. Fewer, better executed sizes get more attention per unit than twenty one rushed exports, and creative quality is one of the few levers left in a programmatic buy where the algorithm handles the rest.
Demand Gen and display are two different spec sheets inside one platform
Display and Video 360 now buys both classic programmatic display and Google Demand Gen inventory, and because they live behind the same login, teams assume one creative spec covers both. It does not. The display specs on this page govern standard banner slots across the open web and apps: fixed pixel dimensions, JPG, GIF or PNG, or an HTML5 ZIP. Demand Gen governs YouTube, Shorts, Discover and Gmail placements, and it works on aspect ratios rather than fixed sizes, with a required 1.91:1 horizontal at 1200 x 628, a 1:1 square at 1200 x 1200, and optional 4:5 and 9:16 vertical assets, plus its own headline and description character limits. Sending a 728 x 90 leaderboard into a Demand Gen campaign will not work, and building only 1:1 and 1.91:1 assets will leave a display line item with almost nothing to serve. The one genuine simplification is that Demand Gen creative specs are identical whether you buy through Google Ads or through Display and Video 360, so a single Demand Gen asset set travels between the two without rework. Plan two asset families per campaign brief, one per surface, and the two most common trafficking failures disappear.

questions
DV360 ad specs: the questions people ask.
What are the DV360 ad specs?
Display and Video 360 splits creative specs by creative type. Image creatives accept JPG, GIF and PNG files up to 4000 x 4000 pixels and 10 MB. HTML5 creatives upload as a ZIP containing up to 100 files, and while the ZIP itself has no size cap, DV360 limits the total file size a browser downloads when the ad serves to 5 MB. Optimized creatives, the responsive format, cap images at 2000 x 2000 pixels and 1200 KB and run on their own character limits.
What ad sizes does DV360 support?
Google documents roughly twenty commonly supported display sizes across four families. Square and rectangle covers 250 x 250, 300 x 250, 320 x 320 and 336 x 280. Skyscraper covers 120 x 600, 160 x 600, 300 x 600 and 300 x 1050. Leaderboard covers 468 x 60, 728 x 90, 800 x 250, 970 x 90 and 970 x 250. Mobile covers 300 x 50, 300 x 100, 320 x 50, 320 x 100, 320 x 480, 360 x 592, 360 x 640 and 375 x 667. Other sizes can serve, because inventory varies by site, app and region.
What is the maximum file size for a DV360 creative?
For image creatives the limit is 10 MB, with a maximum of 4000 x 4000 pixels. That is the platform ceiling, not a target: publishers frequently enforce smaller limits, and a display banner that is anywhere near 10 MB will lose impressions to timeouts. For HTML5 creatives the number that matters is different. The ZIP has no stated size limit, but DV360 caps the total download a user browser performs at 5 MB per served ad.
Does DV360 support HTML5 ads?
Yes. HTML5 creatives are uploaded as a ZIP of up to 100 files and can include .html, .htm, .css, .js, .jpg, .jpeg, .gif, .png and .svg assets plus font files in .dfont, .eot, .otf, .tte, .ttf, .woff and .woff2. Animation is capped at 30 seconds. A single ad may set at most 25 cookies and make at most 100 HTTP calls. Autoplay audio is not allowed and autoplaying video must start muted.
What are optimized creatives in DV360?
Optimized creatives are Google's responsive format for Display and Video 360, assembled from a pool of assets that the platform mixes and matches into variations. You supply one to five short headlines of up to 30 characters, one long headline of up to 90 characters, one to five body text blocks of up to 90 characters, an advertiser name of up to 25 characters, a call to action of up to 15 characters and a display URL of up to 30 characters.
What image sizes do DV360 optimized creatives require?
Optimized creatives take one to five logos, at least one of which must be square, and up to fifteen product or service images. Every image must be JPG or PNG, no larger than 2000 x 2000 pixels, and no heavier than 1200 KB. Square logos use a 1:1 ratio at a minimum of 128 x 128. Rectangle logos use a 4:1 ratio at 512 x 128. Product images need a 1:1 square at a minimum of 627 x 627 and a 1.91:1 rectangle at a minimum of 1200 x 627.
Are Demand Gen specs different in DV360?
The creative specs are the same. Demand Gen buying is available in both Google Ads and Display and Video 360, and the asset requirements, image ratios and character limits do not change between the two surfaces, so one Demand Gen asset set works in either. What differs is the management surface and the reporting around it. Demand Gen specs are also completely separate from the display specs on this page, because Demand Gen runs on YouTube, Shorts, Discover and Gmail inventory rather than standard display slots.
What is the difference between DV360 and Campaign Manager 360 creative specs?
They are close but not identical, and the gap catches teams who assume one spec sheet covers both. Both accept image assets up to 4000 x 4000 pixels. The file size ceiling differs: Display and Video 360 documents 10 MB for image creatives, while Campaign Manager 360 documents 9.5 MB for display creative image assets. If you build a single master set for both platforms, size to the lower number so one asset library passes validation in each.

Demand Gen buying inside DV360 runs on a completely separate spec sheet: Demand Gen ad specs covers the image ratios, asset requirements and character limits for that surface, and the specs are identical whether you buy through Google Ads or Display and Video 360.
For the sizes themselves, Google display ad sizes covers which units carry inventory across the Google Display Network, and the ad resizer covers producing every dimension from one creative rather than exporting each by hand.
If you are buying software rather than checking a spec, creative management platform compares the vendors that automate display production at volume, and display ad maker covers producing a standard banner set without a designer.
