Our Process & Recommendations

To ensure a smooth process and high-quality results:

  • We usually start by creating the Square (1:1) format first.

  • After client feedback (such as updates to text or logos), we roll out the other formats (Story 9:16, Landscape 1.91:1, and Portrait 4:5) for consistency and faster approval.

  • We recommend submitting ads in all formats upfront to maximize your campaign’s potential across different placements and devices.
