This page will help you obtain accurate head measurements for babies, children and adults.
Head sizes vary from person to person, but generally fall into the size categories below. To be sure though, one size does not fit all!
To measure your head circumference, wrap a tape measure around the widest part of your head - over your hair, from your forehead, above your ears and around the back, then round to the front again. Make sure the tape measure is snug - a Hat should fit snuggly; not too tight or too loose. This is the measurement given for Hat sizes, and is the measurement given for the brim of the Hat.
The length of a Hat will vary between styles, but to know the length of your head in relation to the pattern, measure from your crown to the base of your ear and this will give you your ideal head length for Hats.
Patterns contain measurements and sizing based on gauge and number of stitches - if your working gauge is tighter or looser than that given, you may need to adjust your number of stitches accordingly or adjust your needle/hook size.
The finished measurements for Hats listed in the patterns may be slightly smaller than those given below, to ensure the fabric is stretched slightly for a snug fit. The actual difference between the finished size of a Hat compared to the desired size is usually 2in/5cm or 12%, - this is the normal amount of negative ease included within Woolly Wormhead knitted and crocheted Hat patterns.
The other factor that determines fit is personal choice. Some people like their Hats with little or no negative ease for a more casual look, some people prefer a tighter fitting Hat for a sportier look. This preference in fit is also affected by the style of the Hat, so do consider how the Hat will be worn in relation to the measurements given in the pattern. The patterns found on this website not only include a range of sizes but also include the finished measurements - this will help determine which size is the best one to make.
