Answer 1

Using this example you should be able to keep the size fixed.

$(function(){
    $('#jcrop_target').Jcrop({
        onChange: function(){ $(this).setSelect([x, y, x2, y2]); }
    });
});

Answer 2

You can use the aspectRatio option. This will force a square selection

$(function(){ $('#cropbox').Jcrop({ aspectRatio: 1 });

});

Or aspectRatio: 16/9 would make it wide sreeen :-)

You are basically looking for the API section. Having extensively used this plugin myself, I know exactly what you're looking for:

var api;
var cropWidth = 100;
var cropHeight = 100;

$(window).load(function() {

    // set default options
    var opt = {};

    // if height and width must be exact, dont allow resizing
    opt.allowResize = false;
    opt.allowSelect = false;

    // initialize jcrop
    api = $.Jcrop('#objectId', opt);

    // set the selection area [left, top, width, height]
    api.animateTo([0,0,cropWidth,cropHeight]);

    // you can also set selection area without the fancy animation
    api.setSelect([0,0,cropWidth,cropHeight]);

});

Answer 4

you can set the aspectRatio as decimal value

$('#jcrop_target').Jcrop({
    setSelect: [0,0,150,100],
    aspectRatio: 150/100
});
