A LEGO Yellow Submarine 21306 display case should receive the submarine in its chosen supported position. A Beatles figure frame serves a different collection: the four minifigures, possibly Jeremy and selected accessories. Decide which group you are displaying before comparing case dimensions or frame depth.
The submarine and its two display groups have separate references
The official LEGO 21306 specification gives the submarine as over H13 × L25 × W6 cm. It separately gives the submarine stand as over H3 × W11 × D10 cm and the minifigure stand as over W12 × D4 cm and under H1.6 cm.
Do not add the separately published submarine and stand heights to invent a mounted height. Measure the complete arrangement you intend to enclose, including the support’s actual receiving position. The reference dimensions do not define every possible placement of the figure stand beside the submarine.
The set includes John, Paul, George and Ringo minifigures plus a Jeremy figure. Decide whether these stay together on a separate stand, join a scene beside the submarine or move to a figure frame. Jeremy and carried accessories need their own positions; “four figures” does not describe the complete group.
Compare boat cases without double-counting a manufacturer
The following original descriptions were read on 18 October 2026. They are source specifications, not DisplayCasePro measurements or physical-fit and protection tests.
| Source | Published dimensions | Receiving detail |
|---|---|---|
| Wicked Brick | External W33 × D23 × H19.3 cm. | Set and figure studs; lift-away surround. |
| FlyingBox | Case L10.8 × W7.3 × H7.8 inches; inside/outside unlabelled. Base 11.3 × 7.8 inches. | Whole outer base is larger than the stated case footprint. |
| DisplayGeek | H7.8 × W10.8 × D7.3 inches; inside/outside unlabelled. | Explicitly made and shipped by FlyingBox. |
| iDisplayit | Inside L26 × W15 × H20 cm; outside L28 × W17 × H21 cm. | Confirm the selected submarine and separate figure arrangement. |
FlyingBox and DisplayGeek are separate sites, but the reseller identifies FlyingBox as the manufacturer and shipper. Their matching dimension lines therefore do not constitute two independent physical fitting tests. Keep the ordering route separate from evidence about the receiving product.
Wicked Brick’s exterior dimensions cannot be treated as its cavity. Its description identifies locating studs, a magnetic two-tier base and a surround that returns to grooves. Request the current base layout for the submarine, stand, figures and Jeremy rather than assuming every object shown in LEGO’s set inventory has a reserved position.
The same product page says its current printed back replaces the vinyl version visible in older imagery. Confirm the construction for the order you are considering. The printing method does not establish UV filtering, and an older photograph does not resolve the current base or rear revision.
A Beatles figure frame is a separate product with conflicting versions
The sampled MinifiguresDisplay Yellow Submarine frame is for figures rather than the submarine. Its header refers to four figures, while the description discusses four, five or a custom arrangement. Confirm the count and accessory layout for the exact option.
| Source wording | What it describes | Confirm before ordering |
|---|---|---|
| Earlier frame description | 25 × 25 cm exterior, 4.5 cm depth, MDF with satin black finish. | Whether this construction still applies to the selected option. |
| Newer framework description | Solid-wood unibody, 5 cm external depth and 4 cm inner depth. | Actual receiving depth and current material revision. |
| Figure arrangement | Four/five/custom wording alongside a four-figure header. | Beatles, Jeremy, accessories and their receiving positions. |
These descriptions cannot be combined into a single verified specification. Obtain one current drawing identifying the material, outside dimensions, usable depth, connections and chosen figure count. Do not use the frame’s outside depth as accessory clearance.
The page describes LEGO-backed figure connections and removable-front access. Those features do not prove that every carried accessory or Jeremy arrangement fits. Ask for the exact selected layout, including whether the original figure stand is used, omitted or replaced by individual receiving points.
Separate a settled scene from opening the submarine
LEGO describes a removable top, a cockpit for four minifigures, rotating periscopes, propellers and a rudder. Choose the settled positions first. A case that receives the closed submarine does not establish room to lift its top or reach the cockpit while the enclosure remains fitted.
For occasional access, decide how the case opens, where the removed surround rests and where the submarine’s top will be placed. Keep the figure group clear of that handling route. Assembly screws and corner blocks describe construction; they do not automatically create a routine front-access door.
If the goal is simply to see the four Beatles clearly, a dedicated figure frame may serve that part of the collection while the submarine stays elsewhere. If the goal is a complete enclosed set scene, obtain a base layout receiving both stands and the additional figure. The choice follows the objects you want together.
Keep the object list with the usable dimensions
Use the Yellow Submarine boat-or-figures worksheet. Record the support, figure group, selected frame revision and opening sequence. The measurement guide covers complete arrangements; the collection wall guide covers placement around a figure frame.
Common questions
Does the Beatles figure frame also receive the submarine?
The cited frame is described for figures. Its dimensions and connections do not establish a boat enclosure.
Do matching FlyingBox and DisplayGeek sizes independently verify fit?
No. DisplayGeek identifies FlyingBox as the maker and shipper. Confirm the actual product and intended arrangement with the selected ordering route.
