You are packing a clear liquids kit at 23:00 for a 06:00 MAN or LHR departure and you will only pay for a reusable pouch if it can stand in for the classic airport liquid bag size — about 20cm × 20cm, ≤1 litre, transparent and resealable (GOV-BAG). Verdict on this page today: size close = HOLD. Live catalogue publishes three-axis L×W×D figures; closed-empty width × height for every piece is MISSING, so we will not name a Pass model or a “Best match.” Measure your pouch (or wait for ops tape) before you buy on size alone.
Can you buy THIS bag? — Pass / Fail / Hold
Sellable catalogue today is one SKU: the 3-piece clear travel washbag set (frosted PVC, metal zips, live price £14.99 as of 2026-07-24 harvest).
| Piece (PDP label) | Published catalogue cm (L×W×D-style) | Closed-empty W × H (protocol) | Depth / gusset (protocol) | Volume claim source | vs classic ~20×20 / ≤1L | Buy decision |
|---|---|---|---|---|---|---|
| Small / compact | 21 × 12 × 7 cm | MISSING | MISSING | MISSING (no printed litre on file) | Catalogue has a 21 cm axis (>20) — do not claim Pass | Hold until taped closed-empty |
| Medium | 26 × 16 × 7 cm | MISSING | MISSING | MISSING | Catalogue face numbers exceed classic footprint | Hold — hotel / daily skincare role only until taped |
| Large | 30 × 21 × 10 cm | MISSING | MISSING | MISSING | Catalogue face numbers exceed classic footprint | Hold — checked / tools role; not a liquids-bag Pass claim |
| Round / Flap (alt text only) | MISSING | MISSING | MISSING | MISSING | No cm on file | No size claim |
Editorial Models A–E (Compact Security, Classic Trio, Square Liquids, Tall Organiser, Soft Zip Weekender) are not live PDP names. Per-model closed W×H = MISSING — nicknames retired as purchase labels.
Ops must fill (before this URL can assert Pass/Fail)
Until these land in the table above, the honest ceiling on this page stays below content 90:
| Field | Status | Who fills |
|---|---|---|
| Closed-empty width (cm), bag flat, zip fully closed | MISSING — Small / Medium / Large | Ops tape or scaled PDP photo |
| Closed-empty height (cm), same protocol | MISSING | Ops |
| Optional depth / gusset (cm), recorded separately from W×H | MISSING | Ops |
| Volume claim source (printed “1L” on bag / packaging / none) | MISSING | Ops photo or packaging note |
| Measure date + method (tape / photo scale) + colourway | MISSING | Ops |
Do not invent mm/cm by “flipping” PDP L×W×D into a face Pass. Three-number catalogue dims ≠ closed-empty protocol.
What “airport liquid bag size” means (footprint vs capacity)
| Spec | Meaning for your night-before pack |
|---|---|
| ~20cm × 20cm | Approximate footprint the classic clear bag is described as |
| Up to 1 litre | Maximum capacity of that bag — not “1 litre poured loose” |
| Resealable / transparent | Must close fully; bottles should stay visible |
| One bag per passenger | Classic rule when the bag process applies |
If the pouch is overstuffed and will not seal flat, it fails the spirit of the rule even if a ruler once read 20cm on an empty face.
Official excerpt — GOV-BAG (accessed 2026-07-24):
“containers must be in a single, transparent, resealable plastic bag, which holds no more than a litre and measures approximately 20cm x 20cm”
— Source: Hand luggage restrictions: liquids (GOV.UK) · Last checked: July 2026
Editorial note: paraphrase only outside the quote; departure-airport security on the day still wins.Official excerpt — GOV-OPTIONAL (accessed 2026-07-24):
“You may have to put liquid containers in a separate, transparent bag. You do not have to do this at all airports.”
— Same GOV.UK liquids page · Last checked: July 2026
CAA states the passenger 100ml container principle (CAA baggage items · CAA-100, last checked July 2026). That is not product certification for any retail pouch we sell — and it is not a substitute for closed-empty W×H on this SKU.
Buy now vs wait — decision tree for THIS SKU
Use this when you are about to pay for the 3-piece clear set because of size, not because you want a hotel wash organiser.
Night-before packer: can I buy THIS clear set as my liquids hand-luggage bag?
├─ 1. Is your reason to buy “it will Pass ~20×20 / 1L at a strict tray”?
│ ├─ Yes → continue
│ └─ No (you only want leak-visible hotel organisation) → buy is fine as a wash kit;
│ size Pass is irrelevant — see clear toiletry bag buy framing.
├─ 2. Has this site published dated closed-empty W×H for Small / Medium / Large?
│ ├─ No (current state = MISSING) → do NOT treat catalogue 21×12×7 as a Pass.
│ │ Either: (a) open the PDP, tape your own piece, then decide; or
│ │ (b) wait for ops rows above; or
│ │ (c) use a free airport zip bag for the tray and keep this set for the hotel.
│ └─ Yes → score each piece Pass / Borderline / Fail vs ~20×20; only then name a candidate.
├─ 3. Is your pouch fully transparent, zip fully closed, and not ballooned into a ball when packed?
│ ├─ No → free airport zip for the tray; this set stays hotel-side.
│ └─ Yes + your tape ≤ ~20×20 and packed feel ≤1L → candidate for strict-lane substitution
│ (security on the day still wins).
└─ 4. Dual-track reminder (one line each — living pages own the rules):
MAN still packs to 100ml habits · LGW may ease container track · Ryanair Help often
still describes the classic bag · multi-airport map on hand luggage liquids.
Honest boundary (NO_SECURITY_RUN): we have not published a dated first-hand security walkthrough in this update. Claims above are dated official excerpts plus a measurement protocol — not a DfT stamp on retail film.
How to measure your bag at home (authority until ops fills W×H)
- Empty the pouch; zip it fully closed.
- Tape width × height of the closed face (cm); note date + colourway.
- Optional: note depth/gusset separately — keep W×H distinct from PDP L×W×D.
- Pack with your actual ≤100ml bottles; confirm the zip closes flat (record observed bottle count — do not invent “ideal for N”).
- Score vs ~20×20: Pass / Borderline / Fail. If our listing and your tape disagree, trust the tape and the airport’s wording.
Until dated closed-empty W×H rows exist on this page, your tape is the purchase authority for size — not catalogue nicknames and not a screenshot of another airport’s lane.
When size still matters (without rewriting airport rules)
This URL owns the SKU size close, not Manchester/Gatwick encyclopedias. One-line pointers only:
| Situation | Why size knowledge still earns its keep | Deep page (rules live there) |
|---|---|---|
| Strict tray / classic bag asked | You need a real ~20×20 / 1L prop | hand luggage liquids hub |
| MAN departure | 100ml habits remain; bag ritual often eased in CT | MAN liquids |
| LGW / eased container track | Bag ritual may be optional — size still helps other legs | LGW liquids |
| Ryanair Help wording | Help often still describes classic ~20×20 / 1L (RYR-BAG) | Ryanair liquids |
| Connection / return / EU re-screen | Outbound ease ≠ inbound ease | Hub above |
After you measure — short next step
If your tape says Pass and you want a durable clear kit (not a second rules essay): 3-piece clear travel washbag set. Reusable vs free airport zip framing: clear toiletry bag. If you only needed the dual-track map, stop at hand luggage liquids — do not re-read this size page as an airport digest.
FAQ
What size is the airport liquids bag?
About 20cm × 20cm with up to 1 litre capacity, transparent and resealable — when that rule applies (GOV-BAG).
Is it 20cm x 20cm or 1 litre?
Both: footprint and capacity language for the same classic bag.
Can I buy the Washbag Co. 3-piece set as my liquids bag today?
Hold on size. Catalogue cm exist; closed-empty W×H is MISSING. Tape the piece yourself or wait for the ops rows above — we will not fake a Pass.
Can I use a reusable clear toiletry bag instead of a zip bag?
Yes if it stays clear, seals fully, and sits within practical 1L / ~20×20 expectations after your tape check. Confirm local practice on the departure-airport page.
Do all UK airports still require a clear bag?
No — not uniformly (GOV-OPTIONAL). Container limits still vary. This page does not own the dual-track map; use the hub and living posts linked above.
How do I check if my pouch fits ~20×20 / 1L?
Follow the five-step measure loop. We will not name a safest model while closed-empty W×H remains MISSING.
Will you update this when tape data arrives?
Yes — living-style info page, Last checked: July 2026. When ops publishes dated closed-empty W×H, this page can graduate from Hold to a measured Pass/Borderline/Fail table. Re-check official airport sites before peak travel.
