Banner.h

Height of the slot in device-independent pixels. Through 2.4 the spec marked it recommended in all cases; from 2.5 it is an exact height, recommended only when no Banner.format list is sent.

Field facts

Path: imp.banner.h, imp.audio.companionad.h, imp.video.companionad.h
Object: Banner
Type: integer
Requirement: Optional
Added: OpenRTB 2.0
Spec section: 3.2.6

How it is used

Pair it with Banner.w. Inside a companion array, w and h describe the companion slot, not the video player.

Example

Where the field sits in a payload, with everything else left out:

{
  "id": "req-1",
  "imp": [
    {
      "banner": {
        "h": 250
      }
    }
  ]
}

Common mistakes

Sending physical pixels from a high-density screen instead of device-independent pixels.
Sending h without w, which gives the buyer half a size.
