Gauge matters. If you use the same stitches/rows, counts etc...rather than go by measurements and stitch counts with different needle size, you'll change the size of your hat. If you're knitting for unknown folks in a volunteer knit project, it's going to fit someone along the way. If you want an exact fit, you'll have to measure and do your test swatch.
Again, as I did with Steph's Sparkle hat (pattern in the list to the left), I used the Twisted Rib for my cuffs. If you would rather not use the twisted stitches, just use the regular 2 x 2 rib (K2, P2) for each round. Here again, it's up to you how you make your own, which yarn you use, and how you choose to stripe it.
Basic idea:
Knitted in the round in 4 parts, (Part A) 2 x 2 rib of twisted rib knit cuff, (Part B) Stockinette stitch sections, (Part C)shaping for the crown, (Part D) finishing; cut yarn, thread through stitches, fasten off, and wear.

(US) 5 (3.75mm) 16” circular needle, (US) 7 (4.5mm) 16” circular needle, and (US) 7 (4.5mm) double points or 24” circular needle for crown shaping.
Worsted Weight yarn [Label Gauge of yarn 18 sts/24 rows = 4”/10 cm with (US) 8 (5 mm) needles]
K= Knit
P=Purl
Tbl=through back loop
Tog=together
Part A:
With smaller needles: cast on 64, (72, 80, 88) stitches, Join in the round, being careful not to twist stitches.
Knit 2 x 2 ribbing in twisted rib for 6 (6-9, 9, 9-12) rows.
***twisted rib: row 1: *K1 tbl, K1 tbl, P2*, repeat between **’s around
row 2: *K2, P2*, repeat between **’s around
(Note: for teen/small adult and adult large sizes, the extra rounds are for personal preference to create a deeper crown.)
Part B:
Change to larger needles:
Knit in Stockinette Stitch (knit every round) for 24, (30, 32, 38) rounds.
(Note: this is where I like to stripe the colors)
Part C:
Begin crown shaping:
(Note: when stitches get too tight as you decrease, switch to double point needles, or add a second circular needle to finish the hat.)

Part D:
Cut yarn, thread through remaining stitches left on needle, and pull tight. Fasten off (I personally knot the yarn 3 times to make sure after being washed it won’t pull apart.) Weave in ends (beginning tail and all ends from stripes), and wear!
