4. On the *Select measurement option* window select the option:
  1. Existing measurement: To use an existing pre-completed measurement form, open the dropdown menu under **Existing Measurements** and select a pre-completed form.

> [!NOTE]
> **Note:** The Existing measurement is grayed out if an existing measurement does not exist.

  2. Manual Input: To enter new measurements manually, click **Manual Input** and fill in the measurement details directly in the form. ![Select measurement option from existing measurements or manual input in the dialog box.](https://cdn.document360.io/961862ab-d0f2-4d91-bb62-a62ee8184eff/Images/Documentation/create-estimates-with-gaf-quickmeasure-on-servicetitan-mobile-image-aq8jp2ym.png?sv=2026-02-06&spr=https&st=2026-11-01T19%3A55%3A33Z&se=2026-11-01T20%3A55%3A33Z&sr=c&sp=r&sig=MIVsdZv2knxz5%2B9TJVt257kw6CEHN6%2FeLHPUwEHOIEo%3D)
