The captain’s “C” and alternate captain’s “A” go on the front of the jersey in a conspicuous spot, most commonly the upper left chest, standing about the standard height described in official hockey rules in a color that contrasts with the sweater. Left chest is customary, not mandatory: when a crest or sponsor patch blocks that spot, any clearly visible front placement satisfies NHL rules and USA Hockey guidance.


TL;DR:

  • The size and contrast of captain and alternate letters must be roughly three inches high and clearly visible from the stands, according to NHL and USA Hockey rules.
  • The “conspicuous position” for placement allows flexibility, especially when jersey crests or sponsor patches block the traditional upper left chest spot.
  • Proper measurement methods include starting from the neckline and using the jersey’s centerline to ensure consistent, balanced placement across jerseys.
  • Heat-press or sewing methods depend on fabric type and wear, with sewn borders offering durability for heavily washed or contact jerseys.
  • Accurate pre-game checks and recording placement measurements prevent common mistakes like misaligned offset or poor contrast, ensuring clarity and compliance during games.

What NHL and USA Hockey rules actually require

Both governing bodies write the specification the same way: size and contrast matter more than a fixed coordinate. The NHL’s official rules call for a letter approximately three inches high, in a conspicuous position on the front of the sweater, in a color that stands out from the fabric. USA Hockey’s current rulebook uses nearly identical language and directs teams to confirm details against the 2025-29 edition rather than older printed copies.

A few structural rules matter as much as the size spec:

  • A team may dress one captain and up to two alternates, or no captain and up to three alternates.
  • Goaltenders cannot wear the C or an A under NHL rules.
  • Only the captain, or an alternate when the captain is off the ice, may seek a rules interpretation from a referee.
  • “Conspicuous position” is deliberately open ended, giving teams room to move the letter when jersey design gets in the way.

That last point is the practical hinge for everything else in this guide: the rule protects visibility, not a specific inch on the fabric.

How to measure size and color for on-ice visibility

Getting the three inches right starts with a consistent reference point, not a guess. Measure from the neckline seam down and from the jersey’s vertical centerline out, using the crest’s top edge as a boundary so the letter never overlaps it.

  • Start measurements from the neckline baseline, not the shoulder seam, for repeatable results across sizes.
  • Use the jersey centerline to keep the letter balanced left to right relative to the crest.
  • Choose a single bold color with a contrasting outline, or a two-tone embroidered letter, so it reads clearly under rink lighting.

The NHL’s own specification sets letter height at roughly three inches, which is tall enough to read from the stands and on broadcast camera angles without overwhelming the chest area. Matte twill tends to hold contrast better than glossy vinyl under arena lighting, and embroidered letters keep their shape longer than flat heat-transfer material on high-contact areas of the jersey.

Choosing between heat-press, sewing, and adhesive backing

The right attachment method depends on fabric type and how much wear the jersey will see. Heat-press works well on smooth polyester blends for practice jerseys or lower-contact leagues, while sewing holds up better on mesh or moisture-wicking game jerseys that see heavy stick contact and repeated washing.

  1. Place a protective cloth over the letter before applying heat, and slide a barrier layer inside the jersey so adhesive doesn’t bleed through to the back.
  2. Set the iron or heat press to the temperature the letter manufacturer recommends, since fabric blends scorch at different thresholds.
  3. Apply firm, even pressure for the full recommended time rather than repeated short presses, which weakens adhesion.
  4. Let the letter cool completely before flexing or folding the jersey, since heat-bonded adhesive is weakest while still warm.
  5. Test adhesion by gently tugging a corner before game use, and re-press any edge that lifts.

Sewing a perimeter stitch around a heat-pressed letter adds real durability for tournament schedules where jerseys get washed weekly. Expect to recheck adhesion every few weeks of heavy use and touch up corners before they fully separate.

Pro Tip: Keep a spare letter and a travel iron in the equipment bag. A lifted corner is a five-minute fix between periods if you catch it early.

When the standard left chest spot won’t work

Crests, sponsor logos, anniversary patches, and seam lines sometimes make the traditional upper left chest spot impossible without overlap. The rules anticipate this, which is why “conspicuous position” rather than a fixed coordinate is the operative standard.

  • Right chest placement is widely accepted when the left side is occupied by a crest or sponsor mark.
  • Centering the letter slightly higher or lower than usual is acceptable as long as it stays clearly visible from the front.
  • Avoid the back of the jersey, sleeve-only placement, or any spot padding or equipment can cover during play, since none of these meet the visibility standard.

Before locking in an alternate spot, send a photo or diagram to your league or tournament office and get written confirmation ahead of the first game rather than discovering a problem at check-in. Our logo placement guide covers how to plan around crests and sponsor patches so letters, logos, and numbers coexist without overlap.

A step-by-step workflow for measuring and applying letters

Consistent results come from a repeatable process, not eyeballing each jersey individually. This workflow adapts the same measuring logic RNK Apparel uses for name and number placement to captain and alternate letters.

  1. Wash and dry the jersey first so fabric has already shrunk to its final size before you measure anything.
  2. Lay the jersey flat on a hard surface and smooth out wrinkles across the chest panel.
  3. Identify any obstructions, including the crest, sponsor patches, and seams, before choosing a final spot.
  4. Measure down from the neckline baseline and out from the centerline to mark the letter’s top edge with removable tailor’s chalk.
  5. Dry-fit the letter and backing in place without applying heat, checking that it clears the crest and seam lines.
  6. Apply using heat-press or sewing based on fabric type, following manufacturer temperature and pressure settings.
  7. Let the letter cool fully, then check placement standing several feet back to confirm it reads clearly at a glance.
  8. Record the exact vertical and horizontal offsets used so future jerseys in the same size match without re-measuring.

Pro Tip: Write the offset measurements on the jersey’s care tag with a fabric marker so anyone doing a reorder next season starts from the same numbers.

Skipping the dry-fit step is the most common reason teams end up peeling and re-pressing a letter, so treat it as non-negotiable even when you’re working through a stack of jerseys before the season opener.

A pre-game checklist for coaches and equipment managers

A short check before puck drop catches most letter problems before they become a rink-side scramble.

  • Confirm the correct letter type is on each jersey: one C, up to two A’s, and no letters on a goaltender’s jersey.
  • Check that each letter measures close to three inches and contrasts clearly against the jersey color.
  • Run a hand across each letter’s edges to confirm it’s fully attached with no lifting corners.
  • Verify the placement is unobstructed by pads, straps, or gear during a quick warm-up skate.
  • Submit any required roster paperwork noting captain and alternate designations ahead of the league deadline.

Assign one person, usually the equipment manager, to run this check before the first game of the season and again after any full jersey wash. A quick safety-sew or temporary adhesive strip handles most in-rink fixes; anything requiring a placement change should go through the league for approval first.

Where captain letter mistakes usually come from

The two mistakes we see most often are a vertical offset that’s eyeballed instead of measured, and a letter color too close to the jersey’s own shade to read well from the stands. Both are avoidable with a template and a five-minute check before the letter ever touches heat.

For jerseys that see heavy contact, adhesive alone tends to fail before the season does. A stitched perimeter on top of a heat-pressed base solves that, and recording your placement offsets means a reorder next year takes minutes instead of a fresh round of measuring.

FAQ

What side does the Captain C go on?

The upper left chest is the customary spot, but neither the NHL nor USA Hockey rulebook requires a specific side. Any conspicuous position on the front of the sweater satisfies the rule, which matters when a crest or sponsor patch occupies the left chest.

Is number 69 banned in NHL?

This question falls outside captain and alternate letter rules, which govern size, color, and placement rather than which jersey numbers players can wear. Check your league’s current number policy directly rather than relying on placement guidance for an answer.

What side does a captain patch go on?

Left chest is the common default, matching where most jerseys leave open space beside the crest. The governing requirement is visibility and contrast rather than a fixed side, so right chest is equally acceptable when needed.

Where to put captain patch on hockey jersey?

Place it on the front of the sweater in a conspicuous, unobstructed spot, standing about three inches tall in a contrasting color. Upper left chest is standard, with right chest or a slightly adjusted position as the accepted alternative when the left side is occupied.
