Practical guidance
Your next move
Your result is a BMI-based reference. It does not measure body composition, fitness, diet, medical history or readiness for exercise.
Personalized pathway
Guidance relevant to your result
Calculate your BMI above to unlock guidance relevant to your result.
01
Build toward the range
Where you are
Your BMI is below the standard healthy range and below CrewDash candidate guidance.
Your reference
Build consistency before trying to force bigger meals.
Your 3 levers
Fuel
Add one planned eating opportunity every day. A snack or mini-meal is often easier to repeat than simply making every meal much larger.
Protein
Include a useful protein source in each main meal, such as eggs, dairy, fish, meat, beans, pulses or another option that suits you.
Build
If strength activity is appropriate for you, use it to support muscle and function rather than focusing only on increasing the number on the scale.
7-day launchpad
Add one snack or mini-meal you can realistically repeat most days this week.
Check whether each main meal contains a meaningful protein source plus carbohydrates and fats.
Check your weight again under similar conditions next week. Look for direction over time, not daily noise.
Quick check
Am I actually eating consistently, or am I regularly missing meals?
Avoid this
Trying to gain quickly through sweets, sugary drinks or highly processed food alone.
Trusted next steps
If low weight is unexplained, weight has fallen without trying, or eating has become difficult, professional advice is more important than trying to correct the number alone.
Healthy is a range, not a competition for the lowest number.
03
Healthy BMI. CrewDash is tighter.
Where you are
Your BMI remains within the standard healthy range. CrewDash uses a narrower 18.5 to 23 candidate guidance band.
Your reference
Is cabin crew preparation actually your goal? If no, based on BMI alone, there is no reason to treat this result as unhealthy. If yes, think small adjustment, not aggressive dieting.
Your 3 levers
Drinks
Notice what you drink across three normal days.
Extras
Notice extras, snacks and portions without changing everything.
Movement
Notice long inactive periods and find the one lever that genuinely applies.
7-day launchpad
Observe for 3 days before starting a diet.
Change one realistic thing you could still imagine doing several weeks from now.
Check the trend weekly under similar conditions rather than reacting to daily fluctuations.
Avoid this
Crash dieting to correct a BMI that is already inside the standard healthy range.
Trusted next steps
CrewDash guidance reference: {crewReference}. This is a candidate-focused reference, not a medical target. Approximate difference from the current weight: {crewDifference}.
If the target matters, adjust the lever. Do not attack the whole system.
04
Find the lever first
Where you are
Your BMI is within the standard overweight range and above CrewDash candidate guidance.
Your reference
Do not start by searching for the perfect diet. Start by finding the easiest repeatable source of change.
Your 3 levers
Drinks
Review drinks across three normal days.
Food
Review snacks and portions without judgement.
Movement
Review movement. Whichever pattern appears most often becomes the first lever.
7-day launchpad
Complete the 3-day scan before changing everything.
Adjust one drink, snack, portion habit or inactive period that genuinely exists in your routine.
If appropriate, add a manageable amount of walking or another activity you can repeat consistently.
Avoid this
Trying to fix drinks, food, exercise and every habit on the same Monday.
Trusted next steps
Optional first milestone: {fivePercent}. This is a reference milestone, not a compulsory target. CrewDash BMI-23 reference at this height: {crewReference}.
Your BMI is within the standard obesity range and above CrewDash candidate guidance.
Your reference
BMI cannot tell us the full health picture, body composition or fitness level. Do not make BMI 23 your first target. Start with a smaller milestone that you can realistically sustain.
Your 3 levers
Simplify
Identify one regular source of excess energy instead of rebuilding the entire diet overnight.
Move
Begin from what the body can comfortably and safely do now, then build gradually.
Support
Health conditions, medications, pain, breathlessness, mobility limitations or uncertainty can justify professional support before major changes.
7-day launchpad
Take a 3-day snapshot of drinks, snacks, portions, movement and meal patterns without trying to be perfect.
Choose one repeatable change.
Add one repeatable movement habit from the current ability level. Consistency, not intensity, is the launch goal.
Avoid this
Detoxes, diet pills, extreme restriction and promises of very rapid change.
Trusted next steps
First health milestone: {fivePercent}. This is a reference milestone. Existing medical conditions, medicines that affect weight, significant symptoms or uncertainty about a safe starting point can justify professional support.
You do not need the final target today. You need the first move you can repeat tomorrow.
Standard adult BMI interpretation
The ranges at a glance
< 18.5
Underweight. This is below the standard healthy range and below CrewDash guidance.
18.5–24.9
Healthy weight. BMI above 23 remains healthy while sitting above the narrower CrewDash guidance band.
25–29.9
Overweight. BMI is a screening reference and does not diagnose health.
≥ 30
Obesity. A clinician can consider BMI alongside history and other relevant checks.

Put BMI in context
BMI is useful because it is simple. That is also its limit.
Muscle and body composition
BMI cannot separate body fat from muscle, bone or fluid. Athletic and muscular people may be placed in a higher category even when other health markers are strong.
Life stage and medical context
Pregnancy, some health conditions and changes with age can make a standard adult BMI result less informative. Use professional guidance when these apply.
BMI for Cabin Crew and Flight Attendant Candidates
There is no single worldwide airline BMI standard. CrewDash uses 18.5 to 23 as informational candidate guidance only. It is not an official airline rule and does not determine eligibility. Airlines set their own recruitment and medical requirements.
How this tool works
Your measurements are converted locally in your browser. BMI is kilograms divided by metres squared. Standard adult categories are shown separately from CrewDash coaching guidance.
BMI = kg ÷ m² Advertisement
FAQ
Frequently asked questions
Is this an official airline BMI standard?+
No. CrewDash guidance is informational only. Airlines set and change their own recruitment and medical standards.
Does a healthy BMI guarantee I will pass an airline medical?+
No. BMI is one screening value. Airline medicals can include other health, functional and role-specific checks.
Can I mix centimetres with pounds or feet with kilograms?+
Yes. Height and weight units are independent.
Is this calculator for children or teenagers?+
No. This version uses adult BMI categories and is for adults 18+.
Does NoraDash store my measurements?+
No. The calculation runs in your browser. Raw measurements and exact BMI are not sent to NoraDash product analytics.
Sources and methodology
Adult categories follow CDC guidance. General practical context uses official WHO and NHS guidance and remains educational, not personal medical or nutrition advice.
