The Sweet Zzz Organic weighted blanket comes in one size which is queen (60 x 80) and two different weights which are 15lb and 20lb.
It is recommended to use a weighted blanket that is 8% to 12% of your weight. For example, those who are 120 lb to 180 lb could go with the 15 lb while those at 190 lb and above can go with the 20 lb.
Do keep in mind that the weight here is distributed on a queen size of 60 x 80 which means a throw size at 42 x 75 will feel heavier even at the same exact weight.
We noticed that throw sized weighted blankets feel heavier than queen sized and king size feels the lightest because of weight being distributed on a larger surface. Just keep this in mind when your new weighted blanket suddenly feels lighter than the last one you had.
