Cricket helmet size: measuring, the grille gap and the neck guard

How to find your cricket helmet size

A helmet only protects when it sits still on the head. So the cricket helmet size comes from one number: the distance around the head.

Use a soft tailor's tape. Wrap it about 2.5 cm above the eyebrows, over the tops of the ears, and around the widest part of the back of the head. Keep the tape flat and snug, not tight. Read the number in centimetres.

Measure twice and take the larger reading. Do it with the hair as the player wears it on match day. A thick bun or long hair can add a full centimetre.

If there is no tape at home, use a length of string and lay it against a steel ruler. Do not guess from a cap size. Caps stretch and helmets do not.

Reading the size chart

Most helmets come in six sizes. The ranges below are typical, but always check the chart on the product page, because the shell and the padding differ from model to model.

Extra small junior fits about 51 to 53 cm. Small junior fits 53 to 55 cm. Small fits 55 to 57 cm. Medium fits 57 to 59 cm. Large fits 59 to 61 cm. Extra large fits 61 to 63 cm.

When the head falls right on the line between two sizes, pick the smaller one. The foam softens and settles over the first few weeks of use. A helmet that feels a little firm on day one usually feels right by the second week. A helmet that is a little loose on day one only gets looser.

The fit test at home

Once the helmet arrives, do this test before the tags come off.

Put the helmet on and fasten the chin strap. Leave room for one finger between the strap and the chin, no more.

The front edge of the shell should sit about one finger's width above the eyebrows. If you can see the whole sky above the peak, it is sitting too high and is probably too small.

Now hold the grille and try to move the helmet. Rock it side to side and front to back. The skin on the forehead should move with the helmet. If the helmet slides over the skin, it is too big.

Last, have the player hold a batting stance for two minutes. Look for pressure points at the temples or the back of the head. A sore spot after two minutes will be a headache after two hours.

If the shell fits but the padding feels thin, ask for the thicker pad set some models offer. Do not stuff a cloth inside. It moves, and it changes how the shell spreads the force of a hit.

Setting the grille gap

The grille is the steel or titanium cage in front of the face. Its position decides two things: what the batter can see, and whether a ball can get through.

The gap that matters is the one between the peak and the top bar of the grille. A ball must not be able to pass through it. Test this with a real cricket ball, not a tennis ball. Press the ball into the gap from the front. If any part of it reaches the face, close the gap.

Most helmets have an adjustable grille with two or three set positions. Loosen the side screws, move the grille, and tighten them again with the right screwdriver. Check the screws again after the first few sessions, because they can work loose.

The batter should look through the gap above the top bar, not through the bars. Set the batter in a stance and check that the eyes line up with that gap. If the bar cuts across the line of sight, the batter will lift the head to see over it, and that is when a short ball does damage.

Our pick for most buyers is a steel grille. It is heavier than titanium, but it costs far less. A titanium grille saves about 100 to 150 grams, which matters to an opening batter who faces fast bowling for two hours. For a junior or a club player, steel is the sensible choice.

The neck guard

A neck guard is a pair of padded plates that clip onto the back of the helmet. They hang down and cover the base of the skull and the top of the neck, the part a helmet shell does not reach.

Buy one. For any batter who faces bowling above a slow medium pace, it is not optional. A clip-on neck guard usually costs between ₹600 and ₹900 at MRP.

Check two things before you order. First, the guard must match the helmet's fixing points. Most clip onto the rear edge of the shell or onto the back straps, and not every guard fits every helmet. The product page will say which helmets it fits. Second, the guard should hang free. It should touch the neck lightly when the batter looks straight ahead, and it should not push the helmet forward when the batter looks up.

Fit the guard after you have set the grille, not before. Moving the grille can change how the helmet sits, and that changes where the guard hangs.

Sizing for a child who is still growing

Parents often want to buy one size up so the helmet lasts two seasons. Do not do this with a helmet. A loose helmet can turn on the head when it is hit, and the grille can then press into the face.

Buy the size that fits today. Measure the child's head at the start of every season. Most children between 8 and 14 move up one size every one or two years.

A junior helmet with a steel grille usually sits between ₹1,500 and ₹2,500 at MRP. Buying the right size each time costs less than one trip to the dentist.

When to replace a helmet

A helmet is made to take one serious hit. The foam inside crushes to absorb the force, and crushed foam does not fully spring back. So the rule is simple: replace the helmet after any hard blow to the shell or the grille, even if it looks fine.

Replace it sooner if you see any of these. A crack in the shell, however small. A grille that is bent, or that no longer sits level. Foam that has gone flat, crumbly or hard. A chin strap that is frayed or a buckle that no longer clicks shut.

Without a hard hit, a helmet used three or four times a week lasts about three seasons. After that, the foam and the strap wear out from sweat and heat. Mark the month of purchase on the inside of the shell with a marker so you know its age.

To make it last, let it dry in the shade after every session. Do not leave it in a car boot or in the sun. Heat softens the shell and the glue that holds the padding.

Ordering a helmet online

Order by the head measurement, not by age. Write the number down before you open the size chart.

When it arrives, do the fit test indoors with the tags on and the box kept. If the size is wrong, a clean, unworn helmet is much easier to exchange. Check the return window on the product page before you order, whether you pay by COD or prepaid.

For a club or an academy ordering for a squad, measure every player and order by size, not by a single average. Keep one spare in each of the two most common sizes for new joiners.
