I used this and it matched the local storage size here.

function getLocalStorageSize() {
    var key, item, bytes = 0, keys = Object.keys(localStorage);

    for (var i = 0; i < keys.length; i++) {
        key = keys[i];
        item = localStorage[key];
        bytes += key.length + item.length;
    }

    return bytes;
}

To get a somewhat relevant result you can do this:

var size = JSON.stringify(localStorage).length; // size in bytes

This works because localStorage returns the Object containing all data stored in it. If you stringify it you can easily get the length (in bytes) of the string.

I say "somewhat relevant" because when stringifying the Object quotes are added around the keys and this affects the result. You could otherwise, simply iterate through all the keys in localStorage and sum the lengts of the strings found at those keys.
