When sourcing exercise books for educational institutions, specifications matter more than most buyers realize. The wrong paper weight causes ink bleed-through. Incorrect ruling frustrates students. Poor binding falls apart mid-term. These issues damage your reputation with schools and cut into profit margins.
As a wholesale exercise book supplier, I’ve seen importers lose contracts because their products didn’t meet basic school requirements. This guide covers the technical specifications you need to know before placing your next order.
Understanding Paper GSM for Exercise Books
GSM (grams per square meter) measures paper weight and directly affects writing quality. Schools have different requirements based on student age and usage patterns.
Primary School Requirements (60-70 GSM)
Young students typically use pencils and crayons. Lower GSM paper works well for these writing instruments while keeping costs manageable. The lighter weight also makes notebooks easier for small hands to carry. However, avoid going below 60 GSM—thinner paper tears easily and creates frustration for both students and teachers.
Secondary School Standards (70-80 GSM)
Older students use ballpoint pens, gel pens, and sometimes fountain pens. The 70-80 GSM range prevents most ink bleeding while maintaining reasonable production costs. This specification satisfies the majority of educational suppliers serving secondary schools globally.
Technical and Practical Books (80-100 GSM)
Science practicals, technical drawing, and graph work require heavier paper. Higher GSM prevents marker and compass points from damaging pages underneath. Schools running STEM programs specifically request these specifications for laboratory notebooks.
Ruling Types and Their Applications
Different subjects and age groups require different ruling patterns. Understanding these requirements helps you stock the right products for your market.
Four-Line Ruling
Designed specifically for handwriting practice in primary grades. The four parallel lines guide letter formation with consistent baseline, midline, and capital letter height. Schools in markets following British, Indian, and African curricula commonly use this format for language learning.
Single-Line Ruling
The most versatile option for general note-taking. Standard spacing ranges from 8mm to 9mm depending on regional preferences. This ruling type suits secondary students and represents the highest volume category for most notebook distributors.
Double-Line Ruling
Popular in primary schools for early writing development. The double lines help young students maintain consistent letter sizing before transitioning to single-line notebooks. Markets in Africa and the Middle East show strong demand for this specification.
Square Grid Patterns
Essential for mathematics, physics, and technical subjects. Available in 5mm and 10mm squares to match different educational levels. Graph notebooks with precise ruling command premium pricing in most markets.
Blank Pages
Art and drawing classes require unruled pages. These notebooks also serve as sketch books and idea journals. Consider stocking blank-page options alongside ruled varieties to capture this segment.
Standard Size Options
Exercise book sizes follow international standards, though regional preferences vary significantly.
A4 Size (297 x 210 mm)
The largest standard size, preferred for senior classes and comprehensive note-taking. A4 notebooks provide ample writing space but require more storage space in student bags. Government tenders often specify A4 for secondary schools.
A5 Size (210 x 148 mm)
The most popular size globally for educational use. A5 balances writing space with portability. Most wholesale notebook orders center on this specification.
A6 Size (148 x 105 mm)
Compact size suitable for quick notes and vocabulary practice. Primary schools use A6 notebooks for specific subjects. While unit prices are lower, the convenience factor drives steady demand.
Binding Options for Educational Use
Binding quality determines how long notebooks last under daily classroom use. Schools evaluate suppliers partly on how well products hold up through the academic term.
Saddle Stitch Binding
Metal staples through the spine create the most economical binding option. Suitable for notebooks up to 96 pages. Schools accept this binding for standard exercise books where cost efficiency matters most.
Perfect Binding
Glue-bound spines accommodate higher page counts (100-300 pages). The flat spine allows for printing and provides a professional appearance. Long notebooks and comprehensive subject books typically use perfect binding.
Thread-Sewn Binding
Signatures stitched together with thread create the most durable option. This binding withstands heavy use and allows notebooks to lay completely flat when opened. Premium hardcover exercise books benefit from thread-sewn construction.
Hardcover Case Binding
Rigid covers protect pages throughout the school year. Hardcover exercise books serve examination work, project documentation, and long-term reference materials. Schools pay premium prices for this durability.
Page Count Considerations
Different academic needs require different page counts. Understanding usage patterns helps you recommend appropriate specifications.
Standard exercise books range from 32 to 96 pages for daily classwork. Long notebooks with 200-300 pages suit year-long subjects and reduce the need for multiple books. Government tenders often specify exact page counts, so verify requirements before committing to production.
Cover Specifications
Covers protect contents and represent the first quality impression for schools.
Cover Material and Weight
Standard softcover exercise books use 200-250 GSM cardstock. Laminated covers resist moisture and handling wear. For hardcover options, rigid boards with cloth or PU covering provide maximum protection.
Customization Options
Schools increasingly request custom covers featuring their logos and colors. This branding builds institutional identity and prevents notebooks from being mistaken or stolen. Offering cover customization differentiates you from competitors selling generic products.
Quality Standards and Certifications
International buyers expect documented quality assurance. FSC certification proves sustainable paper sourcing—increasingly mandatory for government and international school tenders. ISO 9001 certification demonstrates consistent manufacturing processes.
Beyond certifications, reliable suppliers provide:
- Paper brightness levels (85-95% for comfortable writing)
- Ink bleed-through test results
- Binding strength specifications
- Pre-shipment inspection reports
Regional Specification Preferences
Markets have distinct preferences based on curriculum traditions and climate conditions.
African Markets: Four-line and double-line ruling for primary schools. A5 size dominates. Bright, colorful covers appeal to the educational segment.
Middle East: Arabic ruling for local language, plus standard English ruling. Higher GSM paper preferred due to fountain pen usage in some schools.
Latin America: College-ruled notebooks popular. Bright paper colors for specific subjects (yellow for math, blue for science) common in some markets.
Specification Checklist for Your Next Order
