SIZE & FIT
Compare usable bag dimensions.
Use the usable internal dimensions to compare the full CelloBag range. The self-seal flap sits outside the usable bag area, so measure the complete finished item before ordering.
PACKING NOTE
Measure the complete finished item. Include any envelope, mount, backing board or insert, then choose the first bag whose usable width and length comfortably exceed those measurements.

How to choose the right cello bag size
Start with the complete finished item, not the paper-size name alone. Measure the width and height including any mount, backing board, envelope or insert, then choose a bag with usable internal dimensions slightly larger than those measurements.
A3, A4 and A5 cover the core print formats; 5×7 suits photos and smaller artwork; C5 and C6 suit cards and envelopes; 6×6 and 3×5 cover square and compact items. If you are between sizes, use the full guide before ordering.

How do I choose the right cello bag size?
Measure the complete finished item you are packing, including any mount, backing board, envelope or insert. Compare that measurement with the usable internal dimensions shown for each size.
Do the listed dimensions include the self-seal flap?
No. The dimensions shown are the usable internal bag dimensions. The self-seal flap sits outside that usable area.
Are cello bags the same as cellophane bags?
“Cello bag” and “cellophane bag” are often used as general packaging terms, but our bags are made from crystal-clear 40 micron OPP (oriented polypropylene). See the material comparison.
Can I buy 100 or 200 bags?
Yes. Every standard size is available in 100 Pack and 200 Pack options.
Which sizes work for prints, photos and cards?
A3 and A4 are our core sizes for larger prints and artwork, while A5, 5×7, C5, C6, 6×6 and 3×5 cover smaller prints, photos, cards and paper goods. Always compare your finished item with the usable internal dimensions before ordering.
Where can I check delivery information?
