The Back-to-School sales are in full swing now, and it is time to be finding the perfect backpacks for your children’s upcoming school year. While your children are probably more interested in the fashion statement they are making, parents need to be concerned about the ergonomic value of their choice. Students sometimes carry their entire locker contents on their backs every day. This frequently leads to neck and back issues as well as muscle and joint strains, especially if not carried correctly.
The most important key is to choose backpacks with the right fit. Good quality backpacks use “torso length” as a sizing tool. The bag should cover your child’s torso length from the shoulder straps to the bottom of the bag. To determine this length, measure your child’s back from his C7 vertebra (the bone that sticks out when you bend your neck forward) down to the top of his hip bones (approximately waist level). If the backpack tags do not tell you the torso length, you may need to bring a tape measure with you to the store. (The torso length does not necessarily correspond with a child’s height. A tall person can have a short torso length and vice versa. Some backpacks may have an adjustable torso length; others are fixed.)
The width of the backpack is also important. The backpack should not be wider than your child’s back. Click this link for a chart which gives general guidelines for sizes vs. age. Remember, however, that each body is different, and children do not all grow at the same pace.
The next key to good backpacks is the style. They should have broad shoulder straps with good padding. Be sure the pack has straps for both shoulders so that the weight can be distributed evenly on both sides of the body. You also want to see that the weight inside the pack is evenly distributed. Choosing one with lots of dividers, pockets, and extra compartments will keep the contents stationary and well balanced and will also make the load feel lighter.
The total weight of a filled backpack should not exceed 15% of your child’s weight. For example, a 60 lb. child should not carry a load of more than 9 lbs. (For small children, 10% of their weight should be the upper limit.) If you see your child bending forward when he is wearing his backpack, it is overloaded.
Where each item is placed in the bag is also important. Put the heaviest items so they will be closest to your child’s body; put the lighter items toward the outside. Use the various compartments as much as possible rather than dumping everything in the larger central compartment. It is a good idea when you go shopping to carry some extra items with you to put in the pack to see how comfortable it feels before you purchase.
Backpacks tend to accumulate junk from day to day. Be sure your child is cleaning it out regularly so that he is not carrying any more weight than is actually necessary. Each day have him take inventory to see what items he needs for that day and leave everything else out of the bag.
The backpack should not go below the waist. Shoulder straps need to be adjusted to keep the pack close to the body and high on the back. Be sure your child is actually using both straps so that the weight inside is evenly spread to both sides of his body. A waist strap is also good to help relieve shoulder pressure and to keep the pack from swaying. Your child should use this strap as well if his backpack has one.
Backpacks have become an indispensable part of school life. Choosing one wisely makes a big difference in so many aspects of your child’s school day. Wishing you and your children a great, pain-free school year!
