Measure external dimensions including wheels and handles: length + width + height. IATA guideline sets linear limit at 158 cm (sum L+W+H). When sum ≤158 cm, model usually qualifies as hold baggage on most international routes.
Standard weight allowance on many international economy fares is 23 kg per bag; higher tiers and business class often allow 32 kg. US carriers commonly use pounds: 50 lb equals approximately 23 kg. Overweight fees apply when packed mass exceeds carrier limits.
Typical medium-to-large hardside spinners of similar design measure roughly 65–78 cm (length) × 40–52 cm (width) × 25–32 cm (depth); empty mass commonly 3.5–5.5 kg. If external sum L+W+H stays under 158 cm and packed mass stays within carrier allowance, unit should be accepted in aircraft hold; otherwise request gate check or adjust packing strategy.
Action checklist: weigh empty case with home scale; weigh again after loading using portable luggage scale; keep packed mass ≤ carrier allowance (commonly 23 kg); confirm specific size and weight rules on carrier website before departure; use compression straps, distribute dense items near wheels, place fragile items in middle with padding, secure removable batteries in carry-on.
Hard-shell Upright: Suitability as Hold Bag
Recommendation: Measure external dimensions including wheels and fully-extended handle; keep linear total ≤158 cm (62 in) and packed mass ≤23 kg (50 lb) to comply with most international hold allowances.
Measurement method: place case on flat surface; measure longest external length, maximum external width, and total height from base to highest external point (include wheels, feet, handle knobs). Sum values (L+W+H) to obtain linear total. Record both centimetres and inches.
Structural notes: rigid shell models present fixed external profile; wheel housings and protective bumpers commonly add 3–7 cm to one or more dimensions. Expandable zippers increase depth by 2–7 cm when engaged; carriers assess expanded state at check-in. Empty mass for medium-large hard-side cases typically ranges 3–5 kg; confirm by weighing without contents.
Weight and fee thresholds: many carriers apply standard weight limits near 23 kg (50 lb) for checked-class economy, with higher allowances (up to 32 kg / 70 lb) on premium fares. Overweight charge bands commonly start at 23 kg and escalate at 32 kg. Oversize fees usually apply when linear total exceeds 158 cm (62 in); amounts vary by route and carrier.
Metric | Typical limit | Practical note |
---|---|---|
Linear total (L+W+H) | ≤158 cm / ≤62 in | Include wheels, handles, external pockets |
Weight | ≤23 kg / ≤50 lb (economy) | Higher tiers may allow ≤32 kg / ≤70 lb |
Overweight fee | Varies – common bands 23–32 kg | Pay attention to outbound versus inbound rules |
Oversize fee | Applies when >158 cm / >62 in | Measured at check-in; hard-shell wheels often decisive |
Packing recommendations: weigh empty case before packing; aim for 1.5–2 kg margin under carrier weight cap to avoid surprises at scale. Place dense items close to wheel base to reduce tipping and concentrate volume centrally to minimize bulging at zipper lines. If case has expandable option, measure with zipper both closed and open; avoid relying on zipper expansion when limits are tight.
Pre-travel checks: verify specific carrier policies online within 24–48 hours prior to departure; use handheld luggage scale at home and measure external profile while fully assembled (wheels attached, handle retracted and extended). Keep digital proof of empty-case mass and dimensions on mobile device to contest gate measurements when necessary.
Compare exterior measurements to major airlines’ hold-baggage size rules
Recommendation: Measure exterior height + width + depth including wheels and handles; keep combined linear dimension ≤62 in (158 cm) to avoid oversize charges on most major carriers.
How to measure
- Place case on flat surface; retract handle fully.
- Measure height from wheel contact point to top of case with handle down; measure width at widest point; measure depth from front face to rear face including bumpers.
- Calculate linear dimension: height + width + depth. Convert inches to cm using 1 in = 2.54 cm.
Airline rules summary
- US legacy carriers (American, Delta, United): maximum linear = 62 in / 158 cm; standard hold-baggage weight allowance ~50 lb / 23 kg; oversize fee applies when linear >62 in.
- Major European carriers (Lufthansa, Air France, British Airways): common max linear = 62 in / 158 cm; typical hold-baggage weight allowance often 23 kg; some fare types allow 32 kg.
- Middle East long-haul (Emirates, Qatar): common max linear = 62 in / 158 cm; weight allowance often 30–32 kg depending on cabin.
- Low-cost carriers (Ryanair, easyJet): size and weight limits vary widely; many charge per kilo or impose stricter external-dimension caps; verify policy before travel.
Example comparison: exterior 27 in × 20 in × 12 in → linear 59 in (150 cm) – acceptable with most carriers. Exterior 30 in × 22 in × 12 in → linear 64 in (162.6 cm) – oversize fee likely; confirm carrier policy prior to departure.
- If measured linear >62 in: review fare-class or loyalty allowances that may permit larger linear and higher weight.
- Choose a smaller-case option (aim 24–28 in height) to keep combined dimension under 62 in when loaded.
- Remove or replace removable external parts that add bulk (straps, add-on pockets, aftermarket wheels) to reduce exterior measurements.
- If oversize fees exceed acceptable cost, ship excess items via courier instead of stowing in hold.

How to measure your hard-shell spinner including wheels and handles to avoid oversize fees
Measure height, width, depth including wheels, bumpers, external pockets and any protruding handles; add three results to get linear size used by most carriers.
Tools: rigid tape measure with inch and centimeter marks, flat hard floor, straightedge or book to keep tape perpendicular, smartphone camera for proof.
Step-by-step measurement
Place suitcase upright on hard floor with wheels resting on surface. Align tape measure at floor where wheel contacts floor and run tape to highest rigid point on suitcase body (include corner bumpers and fixed top handle). Record height with handle collapsed.
Extend telescopic handle fully and measure again from floor to top of extended handle; keep larger height value in records.
Measure width across widest side including side pockets and wheel housings. Keep tape parallel to floor and read at suitcase midpoint to avoid bulges at corners.
Measure depth from front face to back-most point of wheel assembly or bumper. If spinner has exposed outer wheel tread, measure to outer tread edge rather than wheel axle.
Check for additional attachments (external straps, ID tags, shoe pockets, garment racks); measure including those items if they increase any dimension.
How to calculate and document
Convert all three numbers to same unit (inches or centimeters). Linear size = Height + Width + Depth. Example: 28 in + 18 in + 12 in = 58 in (147 cm). Round up to nearest 0.5 in or 1 cm to avoid under-reporting.
Take photos showing tape measure against suitcase in each measured configuration (handle collapsed, handle extended, front view, side view). Store measurements and images with purchase receipt and model name to present at check-in in case of dispute.
Determine packed weight and common airline weight allowances
Keep total bag weight under 23 kg (50 lb) to avoid overweight fees on most international and U.S. legacy carriers.
How to calculate packed weight
Weigh empty case on a digital scale; record empty weight. Pack items as planned; weigh loaded case. Subtract empty weight from loaded weight to get net contents weight if needed. Use a portable bag scale hooked to handle or bathroom-scale step method plus subtraction when handheld scale unavailable.
If a handheld scale has a low limit, weigh person holding case on a bathroom scale, then weigh person alone; subtract to obtain case weight. Target loaded weight at least 1–2 kg below allowance to account airport-scale variance and agent rounding.
Common airline weight allowances
Typical rules (examples):
– International legacy economy: 23 kg (50 lb) per hold item.
– U.S. legacy carriers (paid bag): 23 kg (50 lb) per bag; overweight fee often applied between 23–32 kg (50–70 lb).
– Premium cabins / business class / elite status: 32 kg (70 lb) per bag on many carriers.
– Low-cost carriers: 15–23 kg common; some require pre-purchased weight bundles with strict fixed caps at 20 kg.
– Piece-based fares: allowance expressed as number of pieces (1–2) with individual piece weight limits, commonly 23 kg or 32 kg.
If packed weight exceeds allowance, redistribute items into additional bag(s), move heavy garments onto person at boarding, remove nonessential items, or arrange courier shipment. Always check carrier policy online using flight booking code and baggage rules prior to airport arrival.
Pack and distribute items in this hardside case to stay under airline size and weight thresholds
Pack heavy items close to wheel end to keep center of gravity low and reduce strain on handle during weighing.
Place shoes, chargers and dense electronics at base; separate weight between two sides to maintain side-to-side balance within 1–1.5 kg.
Use vacuum or compression bags to shrink bulky garments by 40–60%, creating extra allowance space without adding bulk.
Use packing cubes: dedicate one cube to underwear and socks, one to shirts, one to trousers; position cubes so mass spreads evenly front-to-back.
Pack fragile items in a middle layer surrounded by soft clothing, with rigid pieces oriented toward case shell to absorb impact.
Move spare batteries and toiletry bottles into carry-on to avoid airline hold restrictions and reduce overweight risk inside checked area.
Weigh fully packed case with a portable digital scale; subtract 1.0–1.5 kg margin from published allowance (common tiers: 23 kg, 32 kg). If overweight, shift heaviest nonessential item to cabin bag or worn clothing.
Roll shirts and stack folded trousers along spine to maximize compression; fill seams with socks and belts to eliminate dead space and add padding.
Limit footwear to two pairs and stuff each pair with small items to save space and protect form; wear bulkiest footwear during transit to lower packed mass.
Final check: zip and latch case, weigh again; if scale reads within margin, tag with airline ID and proceed to drop point.
Carrier acceptance: which airlines list a 28 x 20 x 12 in hard-shell spinner as standard hold bag
Recommendation: choose exterior dimensions ≤62 linear inches (158 cm) and packed weight ≤23 kg (50 lb) to qualify as a standard hold bag on most legacy carriers; measure including wheels and handle, weigh loaded case on a luggage scale.
- American Airlines – Size limit: 62 linear inches; typical weight allowance: 50 lb (23 kg) for economy. A 28 x 20 x 12 in case equals ~60 linear inches, so accepted as a standard hold item; overweight fees apply at 51–70 lb, oversize fees apply if >62 in.
- Delta Air Lines – Size limit: 62 linear inches; common economy weight cap: 50 lb (23 kg). Same verdict as above: 28 x 20 x 12 in meets size cap; check fare class for weight allowance and overweight fee tiers.
- United Airlines – Size limit: 62 linear inches; economy weight cap typically 50 lb (23 kg). 28 x 20 x 12 in accepted as standard piece; weight above allowance triggers overweight charge, heavier premium classes may allow up to 70 lb (32 kg).
- Southwest Airlines – Size limit: 62 linear inches; per-piece weight cap generally 50 lb (23 kg). 28 x 20 x 12 in fits size rule; first two pieces accepted with fare rules, fees apply when piece count or weight exceed allowance.
- JetBlue & Alaska Airlines – Both use 62 in size cap and typically 50 lb (23 kg) weight cap in economy. 28 x 20 x 12 in accepted as standard; carry proof of weight at check-in to avoid surprise fees.
- Major European carriers (British Airways, Lufthansa, Air France) – Many operate a piece or weight concept: common size cap = 62 linear inches, common economy weight cap = 23 kg (50 lb). 28 x 20 x 12 in usually qualifies; specific transatlantic fares may allow only one piece at 23 kg, premium classes allow higher weight.
- Middle Eastern carriers (Emirates, Qatar, Etihad) – Policies vary by route and fare: some use piece concept with 23 kg, others allow 30–32 kg per piece on long-haul or premium fares. 28 x 20 x 12 in normally meets dimension limits; confirm weight allowance by ticket class.
- Low-cost carriers (Ryanair, easyJet, Wizz Air, Spirit, Frontier) – Dimension caps often similar (≤62 in) but piece allowances, included baggage and weight caps vary widely; 28 x 20 x 12 in will usually meet size threshold yet may still incur a per-piece fee or be excluded from basic fares. Always verify baggage inclusion before booking.
Quick decision steps at booking or before check-in:
- Measure exterior length + width + height including wheels/handle; calculate linear inches. If ≤62 in, size rule met on most carriers.
- Weigh packed case; if ≤23 kg (50 lb), weight rule met on many legacy carriers. If weight >23 kg, consider redistributing items or upgrading fare class.
- Compare carrier policy linked to booking confirmation; note piece concept versus weight concept differences, and note overweight/oversize fee levels.
- If fee comparison needed: calculate overweight fee versus cost of adding second piece; often adding second piece is cheaper above specific weight thresholds.
Packing tip: place heavy shoes or electronics near rollers to lower perceived length while keeping weight centered; use an accurate luggage scale at home to avoid check-in surprises. Small weather items such as an best ladies telescopic umbrella belong in an outer pocket to keep central compartment weight balanced.
