ms access 2013 custom ribbon height

[Wysy]

Hi,
Is there anyway to decrease the height of a custom ribbon? Currently i use the following code

<customUI xmlns="http://schemas.microsoft.com/office/2009/07/customui">
<ribbon startFromScratch="true">
<tabs>
<tab id="mso_c1.2BEDE7A">
<group id="mso_c3.69A46B">
<button id="VisitEntry" size="normal" label="VisitEntry" imageMso="FileNew" onAction="VisitEntry" visible="true" enabled="false"/>
</group>
</tab>
</tabs>
</ribbon>
</customUI>

It works fine, but i would like to shrink its height. Any ideas?
thanks

No, the ribbon is a fixed height.
