Looking for the metro child ticket age limit in India 2026? The first thing to know is that there is no single nationwide age rule for every metro system. Several metro operators use the child’s height rather than a birthday-based age cutoff when deciding whether a ticket is needed.
That difference matters. A child who is five years old may fall under a free-travel rule in one metro if the child is below the operator’s height threshold, while another operator may apply a different rule. So do not automatically use Indian Railways child-ticket rules, school-age rules or the general legal age of majority when checking a metro fare.

Metro Child Ticket Age Limit: Quick Answer
There is no single India-wide metro child ticket age limit. The rule is set by each metro operator. In the official rules checked for this guide, the criterion is often height rather than age: Chennai Metro refers to children less than 90 cm in height, Hyderabad Metro refers to children below 90 cm, and Bengaluru’s Namma Metro says passengers under 3 feet do not need tickets and that age is not considered.
| Metro system | Child rule found on official source | Key point |
|---|---|---|
| Chennai Metro | Children less than 90 cm in height are exempt from metro fare; CMRL also says this exemption applies to group tickets. | Height-based, not a simple age cutoff |
| Hyderabad Metro | Children below 90 cm can travel free; one child is allowed per accompanying adult. | Height-based and accompanied-child rule |
| Bengaluru Namma Metro | Passengers under 3 feet do not need a ticket; the rule states that age is not considered. | Height-based, with an explicit no-age criterion |
These are operator-specific examples, not a nationwide fare law. A metro system can revise its fare rules, so check the current operator guidance when your journey is close to the date of travel.
Why Metro Child Rules Often Use Height Instead of Age
Age is easy to prove from a date of birth, but a child’s physical size can be more practical for a fare-exemption rule. Metro operators also need a simple rule that station staff can apply quickly at the gate or customer-care counter. This is why a height threshold can appear even when people commonly search for an “age limit.”
For parents, the practical lesson is simple: do not calculate the child’s age first and assume that the answer decides the fare. Start with the metro operator’s current ticket rule. If the operator uses height, the child’s height is the relevant criterion.
- Check the metro system you are actually using.
- Read the current child-fare or ticketing rule on the operator’s official website.
- Check whether the rule uses age, height, or both.
- Look for any accompanying-adult condition.
- If your child is close to the cutoff, confirm at the station before entering the paid area.
City-Wise Metro Child Ticket Rules in 2026
The clearest way to understand the issue is to compare official operator wording. The following examples use published metro-operator guidance available for the systems named below.
Chennai Metro
Chennai Metro Rail Limited states on its group-ticket page that free travel or exemption from metro fare for children less than 90 cm in height is also provided for group tickets. The page was last updated on September 24, 2025. The wording is important because it uses a height threshold rather than a particular birthday.
For a family using a Chennai Metro group ticket, therefore, a child below the stated 90 cm threshold falls under the exemption described by CMRL. Because the published wording is tied to height, parents should not substitute the child’s age for the height check.
Hyderabad Metro
Hyderabad Metro’s official FAQ says that children below 90 cm in height can travel for free. It also states that only one child is allowed per accompanying adult and advises passengers to contact station staff for more information. The operator’s fare-and-ticketing page gives the same basic rule: one child below 90 cm may travel without a ticket with an adult.
This means the question is not simply “Is the child under a certain age?” The operator’s published criterion is height, plus an accompanying-adult condition. A family travelling with two qualifying children should not assume that both children automatically fall under the same free-travel arrangement because the FAQ specifically limits the arrangement to one child per accompanying adult.
Bengaluru Namma Metro
Namma Metro’s official fare-rules page says that passengers below 3 feet in height do not need to obtain tickets and expressly says that age is not considered. This is a particularly useful example for people searching for a metro child age limit because it shows exactly why an age-only answer can be misleading.
The Bengaluru rule uses a three-foot height threshold, not the same 90 cm wording used by Chennai and Hyderabad. Three feet is about 91.44 cm, so the thresholds should not be treated as identical just because both are height-based.
What About Other Metro Systems?
India has multiple metro systems, and there is no safe basis for copying one operator’s child-ticket rule into every other city. A 90 cm rule published by one operator does not automatically become a nationwide metro standard.
| What you are checking | What to verify |
|---|---|
| Child fare exemption | Whether children travel free below a stated age or height threshold |
| Accompanying adult rule | Whether a qualifying child must travel with an adult and whether there is a one-child-per-adult limit |
| Ticket requirement | Whether the child needs a token, QR ticket, smartcard entry or no ticket at all |
| Exact cutoff | Whether the operator says “below,” “under,” or “less than” a particular threshold |
| Recent changes | Whether the operator has published a newer fare or ticketing rule |
If your city is not covered in the table above, use the operator’s own fare-rules or FAQ page rather than assuming that the same child policy applies.
Age, DOB and Height: What Should Parents Check?
For an age-based rule, the date of birth can be decisive because a child may cross the threshold on a particular date. For a height-based metro rule, a date-of-birth calculation may have little or no role in deciding whether a ticket is required.
This is different from many government-job and admission rules, where the notification usually specifies a date of birth cutoff. It is also different from Indian Railways child-fare rules, which use age bands such as below 5 and 5 to under 12. Metro fare policies should therefore be checked separately.
- Age criterion: use the exact DOB and the operator’s stated reference rule.
- Height criterion: use the child’s actual height and the operator’s stated threshold.
- Both criteria: satisfy whichever conditions the operator lists.
- No-age wording: follow the published height or ticket rule rather than importing an age limit from another transport system.
Practical Examples
Example 1: A four-year-old child who is 88 cm tall
Suppose a child is four years old and measures 88 cm. Under a metro rule that says children below 90 cm travel free, the relevant fact would be the child’s height, not the fact that the child is four. The operator’s exact wording still controls the outcome.
Example 2: A six-year-old child who is 92 cm tall
A six-year-old may still be young enough to look like a “child” to a parent, but that does not make the child automatically fare-free. If the metro operator uses a strict height threshold below 90 cm, a child who is 92 cm is outside that height exemption.
Example 3: Two children travelling with one adult
Do not assume that a free-child rule covers every qualifying child in the group. Hyderabad Metro’s official FAQ specifically says only one child is allowed per accompanying adult. Other metro systems may have different arrangements.
Example 4: Child is exactly at the stated cutoff
Pay attention to the wording. “Below 90 cm” and “less than 90 cm” do not describe a child who is exactly 90 cm. When a child is close to the threshold, use the operator’s own wording and ask station staff if there is any uncertainty.
How to Avoid a Ticket Problem at the Station
- Identify the metro operator and city before leaving home.
- Read the latest child-fare or fare-rules page on the operator’s official website.
- Check whether the published rule uses age, height, or both.
- Measure the child if height is the stated criterion and the child is close to the cutoff.
- Check accompanying-adult limits, especially when travelling with more than one child.
- Keep the child’s normal identity or age document available when the operator’s current guidance makes it relevant.
- At the station, ask customer-care staff before entering the paid area if the child is close to the cutoff or the rule is unclear.
The safest approach is to treat the metro operator’s current fare rule as the controlling source for that journey. Do not rely on an old social-media post, a generic “child age limit” chart or a rule copied from another transport network.
Metro vs Railway and Other Child Travel Rules
It is easy to mix up different transport systems because all of them use the phrase “child ticket.” The actual rules can be very different.
| Transport question | Why you should check separately |
|---|---|
| Metro child ticket | Metro operators can use height-based or city-specific fare rules. |
| Indian Railways child ticket | Railway fare treatment uses its own age bands and berth/seat rules. |
| Infant air travel | Airlines can have their own infant, child, document and fare conditions. |
| Unaccompanied child travel | Airline and other transport operators can impose separate age and supervision conditions. |
For the railway case, you can read our Child Train Ticket Age Limit in India 2026 guide. For air travel, see our Infant Flight Ticket Age Limit in India 2026 and Unaccompanied Minor Age Limit in India 2026 guides.
For exact age calculations where an age-based rule really does apply, you can also use the site’s Age Calculator. Just remember that a calculator cannot tell you which transport operator’s fare policy applies.
FAQs
Is there a single metro child ticket age limit for all of India?
No. Metro fare rules are set by the relevant operator. The official Chennai, Hyderabad and Bengaluru examples checked for this guide use height-based rules rather than one nationwide age cutoff.
Is a child below 90 cm free on every metro in India?
You should not assume that. Chennai and Hyderabad publish below/less-than-90-cm rules, but another metro operator can set a different threshold or ticket condition. Check the current rule for your city.
Does age matter in Bengaluru Metro?
Namma Metro’s published fare-rules page says passengers below 3 feet do not need tickets and that age is not considered for this rule.
What if a child is exactly 90 cm tall?
Do not assume that an “under 90 cm” rule includes exactly 90 cm. The wording should be read literally, and station staff can clarify the current implementation.
Can two children travel free with one adult in Hyderabad Metro?
Hyderabad Metro’s official FAQ says only one child below 90 cm is allowed per accompanying adult. A second child should therefore be checked against the operator’s ticket rule rather than assumed to be free.
Do I need the child’s date of birth for a height-based metro fare?
Not necessarily for the fare criterion itself. Where the operator uses height, height is the relevant threshold. However, carry appropriate identification when the current operator rules or station staff require it.

Bottom line: when you search for the metro child ticket age limit in India, do not expect one universal age number. The official examples above show why the right first question is often the child’s height and the specific metro operator’s fare rule. Check the current operator guidance before travel, especially when the child is close to the published threshold.
