Why 4x8 is the default size
Four by eight feet matches standard sheet and plate sizes, fits through most workshop doors on a forklift and leaves room for clamps around a typical frame. On a 1200 mm wide table, an operator standing on either long side can reach the centre line without leaning across the work.
If your parts are longer than 2.4 m, two tables joined end to end often work better than one very long table. See a second table or a bigger one.
Imperial vs metric sizes
| Name | Exact size | Typical 3D table build |
|---|---|---|
| 4x8 ft | 1219 x 2438 mm | 1200 x 2400 mm |
| 5x10 ft | 1524 x 3048 mm | 1500 x 3000 mm |
| 4x6 ft | 1219 x 1829 mm | 1200 x 1800 mm |
Modular tables are built in metric because the hole grid runs at 50 mm or 100 mm spacing. A 1200 x 2400 mm top divides evenly into the grid. Other sizes can be built to your drawing.
Choose the hole system for a 4x8 table
- D16: 16 mm holes on a 50 mm grid. Best for light parts, thin sheet and fine positioning.
- D22: 22 mm holes on a 100 mm grid. A good all-round choice when one table handles small and medium frames.
- D28: 28 mm holes on a 100 mm grid. For heavy frames, thick plate and high clamping force.
The full comparison is in D16, D22 or D28.
Surface, platform height and frame
- Surface. Machined steel, or nitrided for a harder, spatter-resistant face that keeps its accuracy longer.
- Platform height. 100 mm or 200 mm. The 200 mm body gives more side-face area for clamping and a stiffer top. See 100 or 200 mm.
- Frame. Fixed legs with levelling feet for a permanent station, or castors with brakes for a table that moves. See castors and levelling feet.
Ask for the finished weight on the quotation. A 4x8 3D table is heavy, so plan the forklift, crane or pallet jack before delivery.
What moves the cost of a 4x8 table
Steel weight and machining time drive most of the cost: the hole system, platform height, surface treatment and flatness grade all change it. See welding table cost drivers, then send your specification for a quotation.
