| # | Name | Die-cast length | In-universe length | Scale | Notes |
| 1 | Daedalus | 225 mm | 732 m | 1:3253 | Default length of the CG model (TY, SB). Hangar bays just large enough to launch and store F-302s. |
| 2 | Ha'tak | 173 mm | 914 - 1000 m | 1:5283 - 1:5780 | According to concept art. Possibly scaled down to 391 m in Supergate battle (BM). |
| 3 | Death Glider | 105 mm (width 200 mm, height 65 mm) |
8.53 m (width 13.99 m, height 4.50 m) |
1:69 - 1:81 | Default size of the final and best CG version (TY, SB, QMX). The EM model is however based on a fanmade model whose proportions are different. |
| 4 | F-302 | 109 mm | 14.26 m | 1:131 | Default length of the second CG model (TY, SB, QMX). |
| 5 | Prometheus | 180 mm | 516 m | 1:2867 | Default length of the final CG model (TY, SB). Launch bays just wide enough for F-302s. |
| 1a | George Hammond | 225 mm | 732 m | 1:3253 | Same as the Daedalus. |
| 1b | Odyssey | 225 mm | 732 m | 1:3253 | Same as the Daedalus. |
| 6 | Puddle Jumper | 145 mm (TBC) | 8.6 or 12.3 m | 1:59 or 1:85 (TBC) | The first CG model is 8.6 m long (SB), which I believe is accurate to the season 1 physical version. A larger one - 12.3 m according to set plans - was built for season 2. |
| TBA | Destiny | 808 ± 13 m | Possibly default length of the CG model (BM). | ||
| TBA | Wraith Dart | 10 m | Default length of the first CG model (SB). Width (4.5m) fits inner gate diameter. Second CG model seemed too large next to F-302s. | ||
| TBA | Destiny Shuttle | 26.5 m | Default length of the CG model. The physical cockpit interior matches, though the rear area of the set was shortened. | ||
| TBA | Beliskner | (---) | (---) | Unknown. |
| X-301 | 8.8 m | Length should match Death Glider. |
| X-302 | 14.26 m | Same length as an F-302, although the exact length of the X-302/first F-302 CG model is unknown. |
| Tel'tak | (---) | Default length of the best CG model is 14.7 m (SB). Even though the overall size of the interior set is similar, it wouldn't really fit into the CG ship at all. The size of the cockpit windows as well as the opening for the transportation rings in SG1 7x22 and CotG FC indicate a length of approximately 35 m. |
| Al'kesh | 69 m | Default CG size (TY, SB). This roughly matches the cockpit window size. |
| O'Neill class | (---) | Unknown. Likely scaled up next to Prometheus in SG1 6x12; possibly scaled down to 374 m in 9x20 (BM). |
| Seed Ship | (---) | Exact size unknown, 380 - 480 m next to Destiny? |
| Atlantis | 1.33 km | Default size of the first CG model according to Bruce Woloshyn. This is about consistent with the size of the gate room and balcony sets. Second CG model was scaled up to 4.3 km (SB), which makes it large enough for the Daedalus to land between the piers. |
| Aurora class | 1265 ± 15 m | Approximate default CG size (TY, SB). |
| Wraith Shuttle | (---) | Unknown, small enough to fit into Daedalus class launch bay. The schematics in 5x11 indicate a size of 117 x 53 m, but that would be wider than the hangar doors and wouldn't leave enough space for F-302s at the sides. |
| Wraith Cruiser | 600 m | Default size of the second CG model (SB). First CG model is 610 ± 15 m long on 2005 internal scale chart. |
| Wraith Hive | 3292 ± 15 m | Size of the first CG model on 2005 internal scale chart. Fits with size of the cruiser. Schematics with the Daedalus in SGA 2x20 indicate 7500 - 10000 m though. |
| Wraith Super Hive | (---) | Probably same size as a regular hive or slightly larger? |
| Ori Mothership | (---) | Shouldn't be much longer than 400m, if it was supposed to fit through the first supergate, whose segments came through a regular gate. Comparison to people and houses in 9x19 also doesn't make it seem huge. Greatly scaled up next to other ships. |
