SAN FRANCISCO —When planning for a move, most homeowners make an effort to be prepared by packing their household items ahead of time. However, to ensure an efficient move, it’s important to pack properly.

One packing rule is pretty basic: Make sure everything ends up in a box. This may sound simple, but it’s easier said than done. The more loose items you have on moving day, the more time it’ll take to figure out what to do with them. Since most items need to be in a box before they can be moved, having everything packed in advance can save you time (and if your mover charges by the hour, money).

When packing boxes, be sure to consider the weight of the items you’re packing. Heavy items like books and kitchen appliances should be packed into smaller boxes, whereas lighter items like linens and children’s toys can be packed into larger ones. It’s also a good idea to seal all boxes, which will help you avoid spills and lost items. Lastly, label each box with the room it will go into—that way, your movers will know where to put everything when they unload the truck at your new location.
