Computer forms (continuous form paper) in Sri Lanka generally range from about Rs 2,900 for a box of 9.5×11 inch single-ply paper to around Rs 12,500 for a 5-ply carbonless box. At Officestationery.lk, a 9.5×11 1-ply box is Rs 2,900.00, a 2-ply box is Rs 7,500.00, and a 5-ply box is Rs 12,500.00. The exact price depends on three things: the sheet size, the number of plies (copies), and whether the stock is plain or carbonless. This guide explains what drives those numbers so you can match the right form to your printer and budget.
What is computer form paper?
Computer form paper, also called continuous stationery or tractor-feed paper, is fan-folded paper joined in one long strip with sprocket holes punched down both edges. As Wikipedia’s reference entry defines it:
“Continuous stationery (UK) or continuous form paper (US) is paper which is designed for use with dot-matrix and line printers with appropriate paper-feed mechanisms.”
The removable edge strips carry standardised engagement holes that are 5/32 inch (about 4 mm) in diameter and spaced 1/2 inch (13 mm) apart, so an 11-inch deep sheet carries roughly 21 sprocket holes down each side. Those holes lock onto the tractor wheels of impact printers and keep every line aligned during long, unattended print runs in banking, retail and logistics.
What sizes do computer forms come in?
Two North American sizes dominate the Sri Lankan market, and both are what Officestationery.lk stocks:
9.5×11 inch (241 × 279 mm) — the everyday size for invoices, receipts and statements. Once the perforated sprocket strips are torn off, the printable area is close to US Letter.
15×11 inch (381 × 279 mm) — a wide format used for spreadsheets, ledgers and reports that need more columns across the page.
Both sizes are confirmed standard continuous-stationery dimensions, so a printer set up for one width will reliably feed forms from any compliant supplier.
What does “ply” mean and how does it affect price?
“Ply” is the number of copies a single pass produces. A 1-ply form is one sheet; a 3-ply form has three layers bonded together, so one print of an invoice creates an original plus two duplicates. Multi-part forms achieve this with carbonless (NCR) coatings or interleaved carbon, which is why more plies cost more per box.
2-ply: a copy for the customer and a copy for your records.
3-ply to 5-ply: delivery notes, GRNs and tax documents where several departments each keep a copy.

What influences computer form prices?
Plies and carbonless coating
This is the single biggest driver. Each added ply means more sheets and, for carbonless forms, a chemical coating, so a 5-ply box typically costs several times more than a 1-ply box of the same width.
Paper width and weight
Wide 15×11 stock uses more pulp per sheet than 9.5×11, which is reflected in its price. Heavier paper weight (gsm) also adds material cost while improving durability.
Imported raw material and exchange rates
Most paper and pulp used for computer forms is imported, so global pulp prices and the LKR exchange rate feed directly into local shelf prices. A weaker rupee or higher freight costs push prices up.
Are computer forms still worth buying in 2026?
Despite digital invoicing, impact printing on continuous forms remains a steady niche worldwide. According to Business Research Insights, the global continuous form paper market is valued at about USD 1.2 billion in 2026 and is projected to reach USD 1.5 billion by 2035, expanding at a 2.8% CAGR. The report puts it plainly:
For Sri Lankan businesses that still rely on dot-matrix printers for multi-copy invoices, delivery notes and statutory documents, continuous forms remain the most practical and cost-effective option. The standardised sprocket and perforation dimensions mean a single printer setup works with stock bought today or next year.
Frequently asked questions
How much does a box of computer form paper cost in Sri Lanka?
At Officestationery.lk, computer forms range from Rs 2,900.00 for a 9.5×11 single-ply box to Rs 12,500.00 for a 9.5×11 5-ply box. Price depends on size, number of plies and whether the stock is plain or carbonless.
What sizes of computer form are available?
The two standard sizes are 9.5×11 inch (241 x 279 mm) for everyday invoices and receipts, and the wider 15×11 inch (381 x 279 mm) for spreadsheets and ledgers. Both are stocked at Officestationery.lk.
What does ply mean and which should I choose?
Ply is the number of copies produced in one print pass. Use 1-ply for single internal copies, 2-ply for a customer plus a file copy, and 3-ply to 5-ply for documents several departments must each keep.
Are computer forms compatible with all printers?
They are designed for dot-matrix and line printers fitted with a tractor feed. Standard sprocket holes are 5/32 inch (about 4 mm) wide and spaced 1/2 inch apart, so any compliant form fits a tractor-feed printer. They are not suitable for inkjet or laser printers.
How should I store computer forms?
Keep boxes in a cool, dry place away from direct sunlight and moisture to prevent curling or yellowing, and leave the paper in its original wrapping until you are ready to load it.
