To adjust the width  you could wrap your TextField with a Container widget  like so   Container                  width  100 0    child  TextField       I m not really sure what you re after when it comes to the height of the TextField but you could definitely have a look at the TextStyle widget  with which you can manipulate the fontSize and or height  Container                  width  100 0    child  TextField                                       style  TextStyle        fontSize  40 0        height  2 0        color  Colors black                                 Bear in mind that the height in the TextStyle is a multiplier of the font size  as per comments on the property itself      The height of this text span  as a multiple of the font size       When  height  is null or omitted  the line height will be determined   by the font s metrics directly  which may differ from the fontSize    When  height  is non-null  the line height of the span of text will be a   multiple of  fontSize  and be exactly fontSize   height logical pixels   tall    Last but not least  you might want to have a look at the decoration property of you TextField  which gives you a lot of possibilities  EDIT  How to change the inner padding margin of the TextField  You could play around with the InputDecoration and the decoration property of the TextField  For instance  you could do something like this   TextField                                      decoration  const InputDecoration          contentPadding  const EdgeInsets symmetric vertical  40 0
