Start with the intended use of your stamp
The right stamp size depends on what you want to include and where you plan to use it. A simple name stamp will require much less space than a detailed business stamp containing an address, telephone number and logo.
Before comparing stamp sizes, think about where the impression will be used most often.
A small custom stamp may be ideal for:
Names or initials
Loyalty cards
Short reference numbers
Compact labels
Small packaging
One or two short lines of text
A medium or large custom stamp may be more suitable for:
Business contact details
Return addresses
Company logos
Longer messages
Forms and documents
Packaging, paper bags and boxes
Selecting a stamp based on its intended use helps you avoid choosing an impression that is either too small to read or unnecessarily large for the available space.
What does impression size mean?
The impression size is the maximum area your stamp can print. It does not refer to the overall size of the stamp body.
For example, a stamp with an impression area of 38 × 14mm can print a design measuring up to 38mm wide and 14mm high. Your text or artwork must fit within these dimensions.
You do not always need to use the full available area. Leaving a small amount of space around the design can create a cleaner impression and reduce the risk of text or graphics sitting too close to the edges.
A quick guide to choosing your custom stamp size
Follow these four simple steps before placing your order.
Step 1: Prepare your stamp content
Write down everything you want the stamp to include. This could be:
A name
A business address
Contact details
A website address
A short message
A logo or graphic
Only include information that is genuinely needed. Too much content can make an otherwise suitable stamp look crowded and difficult to read.
Step 2: Arrange the information into lines
Decide how many lines you need and consider the length of the longest line.
A name may only need one line while an address stamp might require four or five. If one line is considerably longer than the others, the stamp may need to be wider even if the overall number of lines is fairly small.
You can sometimes reduce the required width by dividing longer information across two lines.
Step 3: Measure the available space
Measure the area where the impression will be placed. This is particularly important when stamping:
Business cards
Loyalty cards
Product labels
Envelopes
Packaging
Small tags
Pre-printed forms
Draw a rectangle using the proposed impression measurements or cut one out of paper. Place it on the item you intend to stamp. This provides a quick visual guide to how much space the finished impression will occupy.
Step 4: Check the design at its actual size
View or print your design at 100% scale before ordering. Check that the text remains clear and that fine details in your logo are still visible.
If you need to reduce the design so much that the wording becomes difficult to read, move up to a larger stamp rather than squeezing everything into a smaller impression area.
Popular self-inking stamp sizes
Trodat Printy self-inking stamps are available in several practical sizes. The following options provide a useful starting point when comparing your requirements.
Trodat Printy 4910 – 26 × 9mm
This compact custom stamp is best suited to approximately three short lines of text. It is a useful option for names, initials, small reference details and brief messages.
Trodat Printy 4911 – 38 × 14mm
With space for approximately four lines, the 4911 is a versatile choice for names, small addresses, contact information and short business details.
Trodat Printy 4912 – 47 × 18mm
The larger 4912 provides space for approximately five lines. It works well for business addresses, office information, longer personalised messages and designs combining text with a simple logo.
Trodat Printy 4913 – 58 × 22mm
Offering space for approximately six lines, the 4913 is a popular option for detailed business stamps. Its wider impression area can accommodate company details, addresses, contact information and many logo-based designs.
These line recommendations are approximate. The correct choice will also depend on the length of the wording, the font and the complexity of any artwork.
What if your custom stamp includes a logo?
Logos often need more space than text alone, particularly when they contain fine lines or small lettering.
When preparing a logo stamp:
Use a clear, high-quality artwork file
Ideally use a resolution above 300 DPI or a vector image.
Avoid very thin lines and tiny details
Check that small wording remains readable
Allow enough space around the logo
Choose a larger impression if the design feels crowded
A simple logo can often sit beside or above your business details. A more detailed design may require a larger stamp to produce a clear and consistent impression.
Should you choose the smallest size that fits?
Not always. Although a design may technically fit inside a small impression area, it might not provide the clearest result.
Choosing a slightly larger custom stamp can:
Make small text easier to read
Give a logo more room
Improve spacing between lines
Create a cleaner-looking impression
Make the design easier to position
The aim is to find the smallest practical size that displays your complete design clearly rather than simply forcing it into the smallest available stamp.
Check your design before ordering
Before completing your order, ask yourself:
Does the design contain all the information I need?
Is the longest line short enough for the selected width?
Is the text clear when viewed at the actual impression size?
Will the stamp fit comfortably on the item or document?
Is there enough room for the logo and text without overcrowding?
Have I checked the measurements with a ruler?
Taking a few minutes to complete these checks can help you order a custom stamp that is practical, clear and suitable for everyday use.

Frequently asked questions
How do I know what size custom stamp I need?
List the text and artwork you want to include then arrange it into lines. Measure the area you intend to stamp and compare it with the impression dimensions shown on the product page.
What is the difference between stamp size and impression size?
The stamp size describes the physical stamp body while the impression size is the maximum area that can be printed onto the surface.
Can I include a logo on a small custom stamp?
Yes, provided the logo is simple and remains clear at the required size. Detailed logos or logos containing small text will usually produce better results on a larger stamp.
How many lines can I fit on a custom stamp?
This depends on the stamp model, font size and length of the text. Compact models may suit around three lines while larger options can accommodate five or six lines.
What should I do if my design only just fits?
Consider moving up to the next stamp size. Additional space can improve readability and prevent the finished impression from looking crowded.
