Gotham now has a number attached to it
LEGO Batman: Legacy of the Dark Knight is currently listed at 24.4GB on Nintendo Switch 2, according to a NintendoEverything roundup that cites Nintendo eShop listings. That is the concrete storage figure digital buyers can work with right now, and it puts the new LEGO Batman game in the same conversation as several larger upcoming Switch 2 downloads rather than the smaller eShop releases that often sit under 10GB.
The immediate catch is that this is a listing-based detail, not a broad technical breakdown from WB Games or Nintendo. The official LEGO Batman site lists the game for Nintendo Switch 2 and says it is available September 18, 2026 on Nintendo Switch 2, with pre-orders open through the Nintendo eShop and other retailers. It also lists the Standard Edition as including the full base game, a pre-order incentive, and “The Dark Knight Returns” Batsuit. What the provided official page does not spell out is a preload start time, a launch-day patch size, or a separate original Nintendo Switch download requirement.
For anyone searching Lego Batman Switch 2 file size or Lego Batman preload details, the safest reading is this: the Switch 2 download has a reported eShop size of 24.4GB, pre-orders are live through official channels, and preload timing remains unannounced in the available source material.
A midweight Switch 2 download, not a tiny LEGO install
At 24.4GB, LEGO Batman: Legacy of the Dark Knight lands below the biggest Switch 2 game in NintendoEverything’s September 13 listing, but well above most smaller upcoming downloads in that same roundup. EA Sports FC 27 is listed at 66.5GB on Switch 2, Granblue Fantasy Versus: Rising Legendary Edition at 37GB, and Fire Emblem: Fortune’s Weave at 29.5GB. LEGO Batman follows at 24.4GB, ahead of Another Eden Begins at 11.6GB, Akiba Lost at 10.6GB, Fading Echo at 7.8GB, Two Point Hospital: Full Health Collection at 5.9GB, Woodo at 5.6GB, Maestro at 3.9GB, and The Walking Dead: Streets of Survival at 2.4GB.
That comparison matters for planning because 24.4GB is large enough to force a storage decision for players juggling multiple digital games, especially if their Switch 2 library already includes sports titles, RPGs, or fighting games with heavier installs. It is not in the 60GB range occupied by EA Sports FC 27, but it is also far from a quick 2GB to 6GB download you can casually squeeze into leftover space.
The file size also fits the shape of a modern licensed action-adventure release. The sources do not provide technical reasons for the 24.4GB figure, so we cannot attribute it to textures, cinematics, open-world density, or voice assets. Still, for buyers, the practical outcome is clear enough: Gotham is being sold as a substantial Switch 2 download, and clearing space before launch is smarter than waiting until September 18.
The original Switch situation is less clear
NintendoEverything’s September 13 roundup covers both Switch 2 and original Switch file sizes, but LEGO Batman: Legacy of the Dark Knight appears in the Switch 2 section only. The same article lists many original Switch downloads, including EA Sports FC 27 at 29.8GB, Akiba Lost at 11.7GB, Woodo at 4.4GB, Another Eden Begins at 4.0GB, Maestro at 3.9GB, and a long tail of smaller releases. It does not provide an original Switch file size for LEGO Batman.
That absence should not be filled in by assumption. The official LEGO Batman site language supplied here says the game is “Available September 18, 2026 on Nintendo Switch 2,” and its Nintendo eShop link points to a Switch 2 product URL. The same source text includes at least one retail link labeled for “Nintendo Switch” at Amazon, while several other retail links identify Nintendo Switch 2. Based on the provided sources, the confirmed Nintendo platform and confirmed storage figure are both Switch 2.
There is a useful distinction here for readers. A story about “Switch and Switch 2 file sizes” can include both platforms across Nintendo’s upcoming download calendar, but that does not mean every game in the list has sizes for both systems. For LEGO Batman Nintendo Switch 2 buyers, 24.4GB is the number to plan around. For original Switch buyers, the supplied material does not confirm a version-specific download size, a release listing, or an upgrade path.
Pre-order is confirmed, preload timing is not
The official LEGO Batman site says pre-orders are available now and lists PlayStation 5, Xbox Series X|S, Steam, Epic Games Store, Nintendo eShop, and physical retailers for the Standard Edition. It also lists a Deluxe Edition, though the provided text cuts off before all of that edition’s official details are shown. Maxi-Geek reports that WB Games released a trailer for a Mayhem Mode coming as part of the Deluxe Edition, arriving September 18, the same day as the Nintendo Switch 2 release.
That helps establish the buying window, but it does not establish preload timing. The phrase Lego Batman preload is likely to pull in players who want to know when they can download ahead of launch. The available sources support only the existence of pre-orders and the reported eShop file size. They do not state when Nintendo eShop preloading begins, whether the full 24.4GB will be available before launch, or whether an additional update will be required on release day.
For digital buyers, the practical guidance is to treat 24.4GB as the base storage target and leave extra room if possible. Nintendo storefront file sizes can change before launch, and the sources here do not rule in or rule out patches, DLC downloads, or edition-specific data. If WB Games or Nintendo publishes a preload date later, that would be a separate confirmed detail.
How LEGO Batman compares with nearby Switch 2 downloads
The Switch 2 download size picture is becoming more varied as more listings appear. In NintendoEverything’s September 6 roundup, Trails in the Sky 2nd Chapter: Nintendo Switch 2 Edition was listed at 33.2GB, Hot Wheels Infinite Rush at 13.7GB, The Legend of Heroes: Trails to Azure at 6.1GB, TCG Card Shop Simulator at 3.7GB, The Legend of Heroes: Trails from Zero at 3.2GB, and Valheim at 210MB. Against that earlier group, LEGO Batman’s 24.4GB sits closer to the large RPG end of the spectrum than to the compact ports and smaller releases.
Across the two cited NintendoEverything roundups, Switch 2 download sizes stretch from Valheim’s 210MB to EA Sports FC 27’s 66.5GB. LEGO Batman is not the largest upcoming Switch 2 download in those lists, but it is one of the heavier ones. It is smaller than Trails in the Sky 2nd Chapter’s Switch 2 Edition and Fire Emblem: Fortune’s Weave, larger than Hot Wheels Infinite Rush, and far larger than the 3GB to 6GB range occupied by several smaller games.
For players who bounce between big tentpole adventures and smaller eShop curios, that difference changes launch-week logistics. A 24.4GB Switch 2 download is the kind of game you want installed before you sit down to play, particularly if your home connection is slow or your storage is crowded. The listing does not tell us anything about performance, resolution, or frame rate, but it does tell digital owners that Legacy of the Dark Knight needs to be treated like a full-size release rather than a lightweight LEGO side download.
Deluxe Edition content could affect planning, but the install impact is unknown
Maxi-Geek reports that the Mayhem Collection DLC for LEGO Batman: Legacy of the Dark Knight includes a new story mission starring The Joker and Harley Quinn, a Mayhem Mode built around time-limited runs across Gotham City, and a Sinister Pack with themed outfits, a Jokermobile, and Batcave customization items. The same report says a new Absolute difficulty level will be added for all players, regardless of version.
Those details matter because edition choice can affect what players expect to download and play on day one. However, the provided sources do not give a separate Deluxe Edition file size, DLC install size, or confirmation that the 24.4GB eShop figure includes every Deluxe Edition component. The official site confirms the Standard Edition includes the full base game and pre-order Batsuit incentive. Maxi-Geek attributes the Mayhem content to the Deluxe Edition and says it arrives on September 18 alongside the Switch 2 release.
Until Nintendo’s store listing or WB Games gives a clearer breakdown, buyers should avoid assuming that every add-on has already been accounted for in the reported Switch 2 download size. If you are buying Deluxe digitally, leave more than 24.4GB free. That is cautious rather than confirmed, but it is the sensible move when day-one DLC, incentives, and potential updates are part of the launch picture.
The smart move for digital buyers before September 18
The confirmed launch target from the official LEGO Batman site is September 18, 2026 for Nintendo Switch 2, and the most useful storage detail available now is NintendoEverything’s reported 24.4GB eShop listing. That makes the core decision fairly simple for digital buyers: if LEGO Batman is a day-one game for you, prepare the space early and watch the Nintendo eShop listing for any change in size or preload status.
The unanswered questions are still important. The supplied sources do not confirm an original Switch file size, do not provide a preload start date, do not list a physical cartridge install requirement, and do not clarify whether Deluxe Edition content changes the download footprint. They also do not provide Switch 2 performance details, so storage size should not be read as a proxy for visual quality or technical ambition.
For now, LEGO Batman: Legacy of the Dark Knight looks like a substantial Switch 2 download sitting below the platform’s largest upcoming installs and above the bulk of smaller eShop releases. Clear roughly 25GB at minimum, leave a cushion if you are buying the Deluxe Edition or expect launch updates, and do not treat pre-order availability as confirmation that preload has already begun.
