What is an oval company stamp?

The oval company stamp (公司橢圓印 / Oval Stamp) sits between the round seal and the sign chop in the Hong Kong stamp lineup. It uses a horizontally elongated double-ring oval — typically 45 mm × 30 mm or 47 mm × 30 mm — combining the round seal's "formal" feel with the sign chop's landscape space for longer text. The outer ring carries the full English company name; the centre fits 2-3 wider Chinese lines, often with a department or sub-entity label below.

Like the round chop, the oval stamp has no specific provision in the Companies Ordinance (Cap. 622) — it is not a Common Seal substitute. Within Hong Kong's local conglomerates, the oval stamp is most commonly used to distinguish a department, branch or subsidiary from the parent company's round seal.

When you'll use an oval stamp

• Department stamp — Hong Kong's larger conglomerates (finance, real estate, retail) often issue an oval stamp to each department with a label like "ACCOUNTS DEPARTMENT", "PROCUREMENT" or "HUMAN RESOURCES" in the centre. Lets internal paperwork show which department approved it at a glance.
• Branch / subsidiary stamp — within a group, a parent company often uses a 41 mm round seal and its subsidiaries use a 45 mm oval with the subsidiary's name in the centre, so users can immediately tell which entity stamped the document.
• Internal approval chop — internal payment requests, expense claims and approvals frequently carry oval "APPROVED" / "RECEIVED" chops to distinguish them from external documents stamped with the round seal.
• Address-stamp alternative — some companies design the oval as "English name + address" and use it directly on invoices or receipts in place of a rectangular address chop.

Design considerations

• Outer text direction — top arc reads left to right naturally. The bottom arc has two conventions: (a) also left to right (reader-friendly), and (b) inside-out so that the start and end of the text are at the bottom (traditional chop layout). The generator defaults to (b); switch manually if you prefer (a).
• Aspect ratio — about 1.5 : 1 (45 mm × 30 mm) is the standard. If your English name is unusually long, scale up to 50 mm × 32 mm; for a more compact look, drop to 40 mm × 28 mm.
• Centre layout — the oval's landscape space is roughly 50% wider than a round seal of the same height, so a 6-8 character Chinese name fits on a single line, where the round seal would have required two.
• Department label sizing — department names sit at the bottom-centre at 60-70% of the main Chinese name's font size so they don't dominate.
• Ink colour conventions — department chops are commonly inked purple or blue to distinguish them from the company's outward-facing black or red round seal.

Ordering the physical stamp

Once happy with the layout, hand the SVG to a stamp shop and specify:

1. Physical size (45 mm × 30 mm is the default; 47 mm × 30 mm also common)
2. Stamp type (pre-inked / self-inking / rubber)
3. Ink colour (purple or blue is typical for department chops)
