# Custom Formwork Stackups

The **Formwork Sizes** tab in the *Formwork Options* dialog enables you to determine Formwork size preferences, including those for custom stackups. The settings you configure in this tab only apply to the current Handset Designer project. For a complete description of all items in the **Formwork Sizes** tab, refer to [*Formwork Sizes Tab*](/v1/docs/formwork-sizes-tab).

WARNING! This software is intended for use by qualified formwork designers and competent persons as defined by OSHA. Use by unqualified persons may result in DEATH, SERIOUS PERSONAL INJURY OR PROPERTY DAMAGE. Loading determined by this software is based on the load-carrying capacity of panels, fillers, ties, and other hardware. The total loads on individual components as well as the loading of the formwork assembly must be considered. Bracing and platform design is to be performed by a competent person before proceeding with the work.
