Example #1 ImagickDraw::setFontSize()
<?php
function setFontSize($fillColor, $strokeColor, $backgroundColor) {
$draw = new \ImagickDraw();
$draw->setStrokeOpacity(1);
$draw->setStrokeColor($strokeColor);
$draw->setFillColor($fillColor);
$draw->setStrokeWidth(2);
$draw->setFont("../fonts/Arial.ttf");
$sizes = [24, 36, 48, 60, 72];
foreach ($sizes as $size) {
$draw->setFontSize($size);
$draw->annotation(50, ($size * $size / 16), "Lorem Ipsum!");
}
$imagick = new \Imagick();
$imagick->newImage(500, 500, $backgroundColor);
$imagick->setImageFormat("png");

The font size taken in parameter is not the size in point (1 point = 1/72 inch) but the font's height in pixel.
Therefore you should do a conversion to have the correct font size if you want to modify a document destined to print.
For example, if your document's resolution is 300ppi, you should add a 25/6 multiplying factor to your fontsize in order to have a correct behaviour of the font.
<?php
$sourceFile='in.jpg';
$textWrite='God is Great';
$x=50;
$y=50;
$fontColor='#000000';
$fontSize=34;
$colorPix=new ImagickPixel ($fontColor);
$image=new Imagick ($sourceFile);
$draw=new ImagickDraw();
$draw->setFontSize($fontSize);//Sets the font pointsize to use when annotating with text
$draw->setFillColor($colorPix);//Sets the fill color to be used for drawing filled objects
$image->annotateImage($draw,$x,$y,0,$textWrite);//Annotates an image with text
$image->writeImage('out.jpg');//Writes an image to the specified filename
