I would use a slightly different approach which gives more flexibility.
Graphics[{Green, EdgeForm[Black], Rectangle[{0, 0}, {2, 1}], (*Green Background*)
Inset[Style["Text", FontSize -> 150, Bold, Black,FontFamily -> "Calibri"],
{0, 0}, {Left, Bottom}]}] (*position and alignment*)

Or some tilting
q = Pi/6;
Graphics[{Green, EdgeForm[Black], Rectangle[{0, 0}, {2, 1}],
Inset[Style["Text", FontSize -> 100, Bold, Black, FontFamily -> "Calibri"],
{0.5, 0}, {-1,-0.5}, {Cos[q],Sin[q]}]}]

Look at Inset
for more options.
For Text in a box
wordbox[text_, fontsize_, fontcolor_, font_, background_] :=
Framed[ImageCrop@Rasterize@Style[text, FontSize -> fontsize, Bold, fontcolor,
FontFamily -> font, Background -> background],
Background -> background, FrameMargins -> 0]
wordbox["Text", 100, Blue, "Calibri", Red]
wordbox["Texture", 100, Black, "Calibri", Green]
