responsive sizes for enfold theme

I noticed the theme only has 3 responsive sizes. Do you know what the standard theme sizes are and if the ones below would work well with the theme? We noticed there were some issues between laptop and desktop screen sizes.

/* Add your Mobile Styles here */
@media only screen and (max-width: 640px){
}

/* Add your Tablet Styles here */
@media only screen and (min-width: 641px) and (max-width: 1023px) {
}

/* Add your Laptop Styles here */
@media only screen and (min-width: 1024px) and (max-width: 1679px) {
}

/* Add your Desktop Styles here */
@media only screen and (min-width: 1680px) {
}
