Short answer: Design certificate artwork at A4 or Letter size (at least 3508 × 2480 px for landscape A4), keep text and the QR code inside a 10 mm safe margin, use two fonts at most, and put the QR code on a plain, light area at roughly 22–30 mm square so any phone can scan it.
A certificate has two jobs: it has to look like it came from a serious organisation, and it has to be easy to check. Good certificate template design serves both. The artwork carries your brand; the layout leaves room for the details that change on every certificate – the name, the course, the dates, the ID – and for a QR code that scans first time.
Key takeaways
- Start from a high-resolution background at the final page size.
- Leave a clear safe margin so the printer never trims anything important.
- Place the QR code on a plain, light area – never over a pattern or photo.
- Test-print one copy and scan it before issuing in bulk.
Certificate template design: what size should it be?
First, design at the size you will print. In other words, certificate template design starts with the paper. For A4 landscape that is 297 × 210 mm, or 3508 × 2480 pixels at 300 dpi; for US Letter, 3300 × 2550 pixels. Working at full resolution keeps signatures and seals sharp in the PDF. In CertiQR you can pick a size preset, so the stored dimensions always match the paper you choose.
Where should the QR code go?
- On a plain area. QR codes need contrast: dark modules on a light background.
- Big enough. Around 22–30 mm square on paper is comfortable; CertiQR enlarges anything that would print smaller than about 4 mm per module.
- Away from folds and edges. Bottom corners work well and leave the centre for the holder’s name.
- With the ID nearby. Print the credential ID under the code for anyone who cannot scan.
Which fonts suit certificate design best?
Use one display font for the holder’s name and one clean text font for everything else. For example, serif and script styles feel ceremonial; sans-serif feels modern and reads well at small sizes. CertiQR bundles open-licence fonts and embeds them in every PDF, so certificates look the same on any device and any server.
How do I lay out the variable details?
- Upload your background under Templates → Add new.
- Drag in the tokens: holder name, award, issue date, expiry, credential ID and QR code.
- Align the name to the centre and size it so long names still fit – test with the longest name you expect.
- Click Test render to produce a real PDF exactly as the server will.
- Print it, scan the QR code with two different phones, then save.
Common certificate design mistakes
- A QR code placed over a gradient or photograph.
- Low-resolution artwork that looks fine on screen and blurry on paper.
- Text running into the trim area, especially on home printers.
- No credential ID printed – so people without a camera cannot check it.

Certificate template design checklist
- Background at 300 dpi for the final paper size.
- A 10 mm safe margin on every side.
- One display font for the name and one text font for details.
- A plain area of about 25 mm for the QR code.
- The credential ID printed next to the code.
- Space for the longest name you expect.
Portrait or landscape?
Landscape is the classic choice for diplomas and course certificates, because it gives long names plenty of room. In contrast, portrait suits licences, inspection reports and compliance documents that carry more text. So choose the orientation that fits the content rather than habit.
Colour and contrast in certificate template design
Dark text on a light background is the safest choice for both printing and scanning. Also, keep brand colours for borders, seals and headings rather than behind body text. Similarly, the QR code needs strong contrast, so never place it on a gradient or a busy pattern.
Testing before you issue
- First, render a test PDF with your longest name and longest course title.
- Next, print it on the paper you will actually use.
- Then scan the QR code with an older phone as well as a new one.
- Finally, view the PDF on a phone, because many holders only ever see it there.
As a result, problems appear on one test certificate instead of on a whole cohort.
In addition, the official WordPress documentation is a useful, independent reference if you want to read further.
Frequently asked questions
QWhat resolution should a certificate background be?
At least 300 dpi at the final size: 3508 × 2480 pixels for A4 landscape or 3300 × 2550 for US Letter landscape.
QCan I use my existing certificate design?
Yes. Upload it as the template background and place the fields and QR code on top. If the document is already finished, however, upload it as your own document and just add the QR code. Either way, good certificate template design keeps the code readable.
QHow big should a QR code be on a certificate?
About 22–30 mm square on paper is easy for any phone to scan. Smaller codes can work, but scanning becomes less reliable, especially from photographs.
Ready to try it?
Design your certificate once and every credential inherits it – with a scannable QR code in exactly the right place. Try CertiQR free for 7 days.
Can I use different templates for different courses?
Yes. Each category can have its own template, so every course or licence can look different.
Which file format should my background be?
Use PNG or JPG at full resolution. Also, export it without the variable details, because CertiQR adds those for each holder.
We build CertiQR, the WordPress plugin for issuing certificates and verifying them with a QR code. We write about credentials, verification and running a certificate programme.
