When to choose bond vs. coated vs. waterproof paper; size chart explanations for technical prints

Choosing the wrong paper or size for technical prints can lead to unclear drawings, wasted time and unnecessary reprints. If you have ever wondered when to choose bond vs. coated vs. waterproof paper; size chart explanations can make all the difference. This guide breaks it down in plain English so you can confidently select the right option for your next print job.

Why paper choice matters for technical printing

Technical prints are about accuracy and readability. Line clarity, contrast and durability all depend on the paper you choose. Architects, engineers and contractors often work in different environments, from clean offices to busy building sites, so paper needs can vary widely.

Understanding the basics helps you avoid common issues such as ink bleed, glare under lighting, or plans tearing on site.

Bond paper: the everyday workhorse

Bond paper is the most commonly used option for technical drawings.

Best for:

• Architectural and engineering plans
• Black and white line drawings
• Office reviews and mark-ups

Bond paper has a smooth, matte finish that keeps lines sharp and easy to read. It is ideal for folding, annotating and sharing. If you are printing standard CAD drawings or planning documents, bond paper is usually the safest and most cost-effective choice.

Coated paper: when presentation matters

Coated paper has a smooth surface that enhances colour and detail.

Best for:

• Colour plans and elevations
• Presentation drawings
• Posters and display boards

The coating helps colours appear more vibrant and images more defined. However, it can reflect light, so it is not always ideal for on-site use. If your technical prints are client-facing or part of a presentation, coated paper offers a more polished finish.

Waterproof paper: built for site conditions

Waterproof paper is designed to withstand moisture, dirt and frequent handling.

Best for:

• Construction site plans
• Outdoor use
• Health and safety signage

These papers are tear-resistant and remain readable even in wet conditions. While they cost more than standard options, they reduce the risk of damaged plans on site. For projects where durability is critical, waterproof paper is a practical investment.

Understanding technical print size charts

Paper size is just as important as paper type. In the UK, technical prints typically follow the ISO A series.

Common sizes explained:

• A0: Large site layouts and detailed master plans
• A1: Floor plans and elevations
• A2: Reduced plans or design reviews
• A3 and A4: Reports, supporting drawings and handouts

Using the correct size ensures drawings are printed to scale and remain legible. The British Standards Institution provides detailed guidance on ISO paper sizes, which you can review on their official resources at bsigroup.com.

Practical tips before you print

• Always check scale settings before uploading files
• Match paper type to how and where the plans will be used
• Consider folding requirements for large plans

A little preparation goes a long way

Understanding paper types and sizes helps ensure your technical prints are clear, durable and fit for purpose. Whether you need everyday bond paper, high-impact coated prints or robust waterproof plans, making the right choice saves time and avoids frustration. A little preparation goes a long way towards professional, reliable results.
