Kids' Life Jackets: Sizing, Fit and the Rules

Sizing up a child’s life jacket for another summer conflicts with the published fit guidance. REI and BoatUS both say not to buy a vest oversized “to grow into”, and their lift test is the reason (REI and BoatUS, checked 2026).

Three things decide it: the size band on the vest, the published fit check, and the wear rule of the state you launch in. This page walks through each one.

Here is why it matters so much. The U.S. Coast Guard’s Recreational Boating Statistics 2024 records that, across all vessel types, 87 percent of drowning victims whose life-jacket use was known were not wearing one, and that drowning caused 76 percent of fatal boating incident victims where the cause of death was known.

The Coast Guard requires a device of appropriate size and fit under 33 CFR 175.21, used according to its label under 33 CFR 175.15(a) (U.S. Coast Guard, verified 2026).

This page summarizes published safety guidance. It is not a substitute for instruction, and conditions on your water may differ. Check the current rules for the state and water you paddle.

Children are sized on weight, not age, and the printed band on the vest names the child it fits (REI, Stohlquist and Stearns, checked 2026). REI and BoatUS both say to buy the band that matches rather than the next size up (checked 2026).

The Coast Guard’s requirement is a device of appropriate size and fit under 33 CFR 175.21, which a tightened oversized vest does not satisfy (U.S. Coast Guard, verified 2026).

Key Takeaways

The short version comes first: a child’s life jacket must fit snugly and must not slip above the chin and ears when the child is lifted by the shoulders (REI and BoatUS, checked 2026).

Here are the four things to know before you buy.

REI, Stohlquist, and Stearns publish infant vests for 8 to 30 pounds (lb), child vests for 30 to 50 lb, and youth vests for 50 to 90 lb, sized by weight and chest rather than age (2026).
Inflatable life jackets are not approved by the U.S. Coast Guard for users under 16 years old, according to the Oregon State Marine Board, so your child must wear inherently buoyant foam (2026).
Stohlquist and REI describe a padded head-support collar that keeps the head above water, a grab handle at the top-back for quick retrieval, and a crotch strap that stops the vest riding up over the head on child vests under 50 lb (2026).
The Coast Guard’s 33 CFR 175.21 requires a device of appropriate size and fit (U.S. Coast Guard, verified 2026), and REI and BoatUS both say to buy the band that matches rather than a size to grow into (checked 2026).

Child Life Jacket Size: Weight Classes for Infants, Kids, and Youth

Life Jacket Weight Classes for Children

REI and manufacturers Stohlquist and Stearns divide children’s life jackets into three weight groups, 2026. ¹ Here is how the infant and child vests and youth vests break down.

Class	Weight Range (lb)	Weight Range (kg)
Infant PFD	8 to 30	3.6 to 13.6
Child vest	30 to 50	13.6 to 22.7
Youth vest	50 to 90	22.7 to 40.8

Source: REI, Stohlquist and Stearns published sizing charts, 2026.

Sizing depends on weight and chest measurement, not age (REI, Stohlquist and Stearns, checked 2026). The Coast Guard requires a device to be used according to its label under 33 CFR 175.15(a), and to be of appropriate size and fit under 33 CFR 175.21 (U.S. Coast Guard, verified 2026).

So weigh your child first, then read the printed band and buy the vest that matches it rather than the next size up (REI and BoatUS, checked 2026).

Why an Oversized Vest Fails the Fit Rule

Buy the band that matches your child’s weight rather than the next size up (REI and BoatUS, checked 2026). A device that is not of appropriate size and fit does not meet 33 CFR 175.21 however tightly it is strapped (U.S. Coast Guard, verified 2026).

Why Kids Under 16 Need Foam, Not Inflatable, Life Jackets

Inflatable life jackets are not Coast Guard approved for users under 16, and there are no approved child-sized inflatables, so a child wears an inherently buoyant foam vest (Oregon State Marine Board and the U.S. Coast Guard, accessed 2026). ²

An adult belt-pack inflatable does not satisfy that, since the approval limit is on the wearer’s age rather than the device’s owner (Oregon State Marine Board and the U.S. Coast Guard, accessed 2026).

The Coast Guard’s 2023 boater’s guide gives these federal basics for PFDs on your boat:

One wearable Coast Guard approved PFD for each person on board (U.S. Coast Guard, verified 2026).
Each PFD in serviceable condition (U.S. Coast Guard, 33 CFR 175.23, verified 2026).
Each PFD readily accessible rather than stowed away (U.S. Coast Guard’s 2023 boater’s guide).
Of appropriate size and fit for its wearer (U.S. Coast Guard, 33 CFR 175.21, verified 2026).

For a child under 16 that device is a foam vest, since no inflatable is approved for that age (Oregon State Marine Board and the U.S. Coast Guard, accessed 2026).

Safety Features on Child Vests That Youth Vests May Skip

Stohlquist and REI publish three features on child vests under 50 pounds that adult vests often leave out (Stohlquist and REI, checked 2026). ³

Padded head-support collar, which they describe as keeping the head above water and helping the child float face-up.
Top-back grab handle, for retrieval.
Crotch strap, which they describe as preventing the vest from riding up over the head.

Those are the features their published descriptions name, and they are why a child’s vest is built differently rather than simply smaller.

What Changes When Your Child Moves to a Youth Vest

Youth life jackets resemble adult vests and may leave out all three of those features (Stohlquist and REI, checked 2026). Youth foam vests mirror adult features such as side panels and arm holes while being sized by weight (REI, Stohlquist and Stearns, checked 2026).

The Shoulder-Lift Fit Test, Step by Step

REI and BoatUS publish the same fitting test (REI and BoatUS, checked 2026).

Buckle the vest snugly around your child’s torso.
Lift your child by the PFD shoulders.
A correctly fitted vest “will not slip above the child’s chin and ears” (REI and BoatUS, checked 2026).
Do not buy a vest oversized “to grow into” (REI and BoatUS, checked 2026).

That lift test and the instruction not to buy oversized are what REI and BoatUS publish (checked 2026). A vest that fails the test is not a device of appropriate size and fit under 33 CFR 175.21, however tightly it is strapped (U.S. Coast Guard, verified 2026).

Which Rule Applies to Your Paddling Trip: Federal vs. State

Federal law sets a baseline that a state rule can displace. Under 33 CFR 175.15(c), children under 13 must wear an approved PFD while a vessel is underway unless they are below decks or in an enclosed cabin (U.S. Coast Guard, verified 2026). ⁴

Under 33 CFR 175.25, where a state has established its own child wear requirement, that state requirement applies on its waters instead (U.S. Coast Guard, verified 2026).

Ohio’s own rule, for example, reaches children under 10 on vessels under 18 feet, so an 11-year-old is outside it (Ohio Rev. Code § 1547.24, verified 2026). The District of Columbia counts as a state for this purpose (U.S. Coast Guard Hearing Office, Case 5762861, 2020).

So check both: the launch state’s own rule, and the federal rule where the state has none, which is how 33 CFR 175.25 allocates them (U.S. Coast Guard, verified 2026).

How Much State Ages Vary

The age your child must wear a life jacket depends on where you paddle. Florida requires children under 6 to wear one on any vessel under 26 feet that is underway (Fla. Stat. § 327.50, verified 2026). Michigan requires children under 6 on the open deck (MCL 324.80142, verified 2026). Minnesota sets the age at under 10, where the child is not below the top deck and the vessel is not anchored (Minn. Stat. § 86B.501, verified 2026), and Ohio requires children under 10 on vessels under 18 feet (Ohio Rev. Code § 1547.24, verified 2026).

Starting January 1, 2026, Maine requires children under 13 to wear an approved PFD while a recreational watercraft is underway. The rule excepts a child below decks or in an enclosed cabin and does not apply to a watercraft with a Coast Guard certificate of inspection (12 M.R.S. § 13068-A, verified 2026).

Pennsylvania requires children 12 and under to wear one while underway on boats 20 feet or shorter and on all canoes, kayaks and paddleboards (58 Pa. Code § 97.1, verified 2026). New York requires children under 12 to wear one while the vessel is underway, with an exception for a child in a fully enclosed cabin (NY Navigation Law § 40, verified 2026). California requires children under 13 to wear one while a vessel is underway, with exceptions for an enclosed cabin and for emergency rescue (Cal. Harbors & Nav. Code § 658.3, verified 2026). Wisconsin sets no state child-wear age, so the federal under-13 rule governs on federal waters there (Wis. Stat. Ch. 30 and 33 CFR 175.15(c), verified 2026). The Coast Guard Hearing Office article by Danielle Davis states that the federal age applies where a state has no statute (U.S. Coast Guard Hearing Office, 2020).

Whatever the age, the device must be an approved foam PFD rather than an inflatable, since inflatables are not Coast Guard approved for anyone under 16 (Oregon State Marine Board and the U.S. Coast Guard, accessed 2026).

Child Life Jacket Wear Ages by State

State child-wear rules differ, and a state rule displaces the federal one on that state’s waters under 33 CFR 175.25 (U.S. Coast Guard, verified 2026). ⁵ This table covers nine states, not fifty, and gives each state’s own age and the conditions attached to it.

State	Child Wear Age	Statute
Florida	Under 6, on vessels under 26 ft underway	Fla. Stat. § 327.50
Michigan	Under 6 on open deck	MCL 324.80142
Minnesota	Under 10, when not below the top deck and not anchored	Minn. Stat. § 86B.501
Ohio	Under 10 under 18 ft	Ohio Rev. Code § 1547.24
Maine	Under 13 while a recreational watercraft is underway; below-deck, enclosed-cabin and inspected-vessel exceptions	12 M.R.S. § 13068-A
Pennsylvania	12 and under while underway on boats 20 ft or shorter and all canoes, kayaks and paddleboards	58 Pa. Code § 97.1
New York	Under 12 while underway; fully enclosed cabin exception	NY Navigation Law § 40
California	Under 13 while underway; exceptions for an enclosed cabin and emergency rescue	Cal. Harbors & Nav. Code § 658.3
Wisconsin	Federal under-13 rule applies on federal waters; no separate state requirement	Wis. Stat. Ch. 30

The ages spread out. Florida and Michigan set theirs at under 6 (Fla. Stat. § 327.50 and MCL 324.80142, verified 2026). ⁵ Minnesota and Ohio reach under 10, Minnesota where the child is not below the top deck and the vessel is not anchored, Ohio on vessels under 18 feet (Minn. Stat. § 86B.501 and Ohio Rev. Code § 1547.24, verified 2026).

Maine, Pennsylvania, New York and California land between 12 and under 13, but their conditions differ. Maine, Pennsylvania, New York and California apply their child rules while the craft is underway; the table records the principal vessel and cabin qualifications for each (12 M.R.S. § 13068-A, 58 Pa. Code § 97.1, NY Navigation Law § 40 and Cal. Harbors & Nav. Code § 658.3, verified 2026). Wisconsin has no state age, so the federal rule governs on federal waters there (Wis. Stat. Ch. 30 and 33 CFR 175.15(c), verified 2026).

Where the state has its own rule that is the one that applies, and where it has none the federal rule does (U.S. Coast Guard, 33 CFR 175.25, verified 2026). Size the vest to the child’s weight, run the shoulder-lift check, and read the launch state’s rule before boarding.

Cold-Weather Rules That Apply to All Ages

New York, Pennsylvania, Connecticut and Massachusetts impose all-ages paddlecraft wear during the cold months, adults included (NY Navigation Law § 40, 58 Pa. Code § 97.1, Conn. Gen. Stat. Title 15 and 323 CMR 2.07(10), verified 2026).

New York: all ages on vessels under 21 feet, November 1 to May 1 (NY Navigation Law § 40, verified 2026).
Pennsylvania: everyone on paddlecraft, November 1 to April 30 (58 Pa. Code § 97.1, verified 2026).
Connecticut: manually propelled vessels, including canoes and kayaks, October 1 to May 31 (Conn. Gen. Stat. Title 15, verified 2026).
Massachusetts: canoes and kayaks, September 15 to May 15 (323 CMR 2.07(10) and Mass.gov, verified 2026).

The Massachusetts Seasonal Window

Massachusetts applies its rule to canoes and kayaks under 323 CMR 2.07(10), whose text sets the period as January 1 to May 15 and September 15 to December 31 (323 CMR 2.07(10), verified 2026). Mass.gov’s boating-safety page describes the same mandatory-wear window as September 15 to May 15 (Mass.gov, verified 2026).

These are two ways of describing the same annual window across New Year: September 15 through May 15. The regulation divides it into the portions before and after January 1.

Planning Around These Windows

None of those four codes carves out an exception for adults (NY Navigation Law § 40, 58 Pa. Code § 97.1, Conn. Gen. Stat. Title 15 and 323 CMR 2.07(10), verified 2026).

Some states are also looking at broader protections. The Pennsylvania Fish and Boat Commission discussed extending its seasonal period toward June 1 in 2023 remarks, though it did not adopt that change. ⁶

A New Jersey seasonal all-ages requirement could not be confirmed against an official source, and the confirmed New Jersey rule is child under-13 wear (N.J.S.A. 12:7-56, verified 2026).

Make Your Choice Clear

The result is to weigh your child, then match that weight to the printed band and buy the vest that fits it rather than the next size up (REI, Stohlquist and Stearns, checked 2026).

Buckle the vest snugly and lift by the shoulders: a correctly fitted vest “will not slip above the child’s chin and ears” (REI and BoatUS, checked 2026).

Use a foam vest for a child under 16, since no inflatable is Coast Guard approved for that age (Oregon State Marine Board and the U.S. Coast Guard, accessed 2026). Read your launch state’s own rule, which displaces the federal age on that state’s waters, and the federal rule where the state has none (U.S. Coast Guard, 33 CFR 175.25, verified 2026).
