To keep your workflow smooth, it’s important to always have the right paper stocked up. You’ll find a wide range of paper sizes and weights suitable for every type of printer, from home inkjets to heavy-duty office copiers. Stocking up now ensures you’ll never run out when it matters most
Buy Copier paper for the office
Do you need reliable copier paper for your office or home office? Most standard printers use A4 paper size, while larger multifunction printers often require A3 paper size or even A2 paper. For companies that print in high volumes, buying in bulk is the smartest move—not only does it save money, but it ensures your office never runs dry during busy periods.
Different businesses have different needs: A4 paper is perfect for everyday printing, A3 is popular for architects and designers, and smaller A6 sheets are useful for notes, handouts, or marketing flyers. If you’re unsure which type of paper best suits your setup, read our blog on choosing the best printer paper.

What paper weights for what project?
Paper weight plays a big role in how your final document looks and feels. Standard 80gsm paper is ideal for everyday printing, while heavier 100–120gsm sheets are perfect for professional reports or letterheads. For presentations, 160–200gsm adds a premium touch, and thicker 250–300gsm paper is best suited for covers, menus, or invitations. Choosing the right weight ensures durability and a professional finish.

Common questions
What is the most common paper size for printers?
The most common size for everyday printing is A4, which is widely used in homes, schools, and offices. At 123ink.ie, we stock a full range of A4 paper in different weights and pack sizes, so you can choose between reams, boxes, or pallets depending on your printing needs.
Which paper weight should I use for professional documents?
For professional reports, CVs, proposals, or company letterheads, a slightly heavier paper weight makes a big difference. We recommend 100–120gsm paper for a polished, high-quality finish. Our 123ink.ie own-brand premium paper in this weight range is perfect for achieving crisp text and sharp graphics.
Can I use A3 paper in a standard home printer?
Most standard home printers only take A4 sheets, but many multifunction or office-grade printers can handle A3. Always check your printer’s manual before buying. At 123ink.ie, we offer a wide range of A3 paper suitable for larger print jobs such as posters, architectural drawings, and presentations, ensuring you always have the right fit for your device.
