Resize and Relocate

To change the size of the Tooltip, specify the height and width options. Note that the Tooltip's arrow takes its share of the overall size.

$(function() {
    $("#tooltipContainer").dxTooltip({
        target: "#image",
        showEvent: 'dxhoverstart',
        hideEvent: 'dxhoverend',
        height: 70,
        width: 200,
        contentTemplate: function (contentElement) {
            contentElement.append(
                $("<p />").text("Tooltip content")
            )
        }

If you need to position the Tooltip against a certain side of the target element, set the position option.
