Mobile development is unique, since we are designing for thousands of screen sizes. We have a figma design that takes only one size into consideration. In order to still maintain the look of your figma design no matter the type of phone or the screen size, we develop this package to automatically adjust based on the MediaQuary of the phone. You just design as given in the figma, while the plugin does the adjustment work


  1. For automatic adjustment of the sizes of container and sizeboxes
  2. For automatic adjustment of any white spaces, images, icons, any object that have to deal with sizes.
  3. For automatic adjustment of text. We advise to make use of the height adjustment for text.
  4. For padding automatic adjustment.
