Need all textframes in equal width and height

Hi All,

Request:

I need all the text frames in equal width and equal height in my active document.

Trying code:

var myDoc = app.activeDocument

var myTF = myDoc.textFrames.everyItem().getElements()

alert(myTF.length)

app.activeDocument.viewPreferences.horizontalMeasurementUnits = app.activeDocument.viewPreferences.verticalMeasurementUnits = MeasurementUnits.MILLIMETERS;

for(k=0; k<myTF.length; k++)

{

    myTF[k].geometricBounds[3] = myTF[k].geometricBounds[1]+125    //Doubt this line

    alert(myTF[k].geometricBounds[3])

    }

Could anyone give solution for my request.

Thanks
