How you calculate timeline for particular project?

- Timeline of the project can be calculated by doing 2-3 meeting with the client so that you can accurately get what they need.

- After the meeting, I usually create a proposal with cost and the deliverables and send it to client for approval.

- And in the propsal, I specifically describe how many days it'll take in each UX steps like Research or Wireframes.

- And you'll get that by your experience on working on different type of products. It usually takes me a month to fully design a product, if client is active.
