I designed a launch ad set for a placeholder cuffless blood-pressure ring. Three concepts each answer one stated feature: cuffless (the cuff struck out beside the ring), calibration-free (zero steps) and continuous (a whole-day trace against three spot readings, labeled illustrative). Six statics come at Meta's recommended sizes, 1440×1800 for feed and 1440×2560 for Reels, with two six-second videos (24 fps, H.264, stereo AAC). Every text box sits inside its placement's safe zone (for Reels, 14% top, 35% bottom and 6% sides) with at least 18 px to spare. Headlines are at most 27 characters and primary text 50 to 150, all text pairings clear 4.5:1 contrast, and every text box still fits with copy 135% longer. Each line is tagged with the claim it depends on so approved wording can replace it before launch, and asset IDs encode concept, format and version so launch results group by variable.
