code in each of them.
set(gcbf,'Position',[420 520 150 190])

it manually.

normalized.AlsosetthefontSiz e of both buttons to 10. Make sure that
the
fontUnits property for both buttons is set to p oints.

ResizeFcn in the Property Inspector and insert the following code into it.
function uipane l1_R esizeFcn(hObject, e vent data, handles)
.
.
.
set(hObject,'Units','Points') % Was normalized
panelSizePts = get(hObject,'Position'); % Now in points
panelHeight = panelSizePts(4);
set(hObject,'Units','normalized'); % Now normalized again
% Keep fontsize in constant ratio to heigh t of panel
newFontSize = 10 * panelHeight / 115; % Calculated in points
buttons = get(hObject,'Children ');
