The best acrylic glass panes, compared.
Top pick: GSHUR acrylic sheet, 58 × 43 cm, 3 mm Best value: GSHUR A4 acrylic sheets, 3 mm, pack of 2 – About £6.99 for two 3 mm A4 sheets, with 4.5 from 1,156 ratings. The material field says Plastic. Updated 22.10.2026.
An acrylic glass pane is a flat clear sheet of, sold as acrylic, or plexiglass, and used in place of glass for frames, craft, sheds and greenhouse repairs. What matters is the stated thickness, the measured size against the rebate, and whether the sheet is actually acrylic. The five-pack is titled as acrylic, while a verified UK review and the listing bullets identify. Peel the masking film on both faces before you judge clarity, and do not treat a marketplace unbreakable bullet as a test. Roof sag at 3 mm is the deduction, not a size conflict. Thickness, material and the order of checks are in the [acrylic glass pane buying guide](/hub/diy-supplies/acrylic-glass-pane/sub/acrylic-glass-pane-buying-guide). Perspex's own data, not these listings, put clear cast sheet above 92 percent light transmission at 3 mm and BS 476 Part 7 Class 3 only from 3 mm upwards. That is a surface-spread class, not fire-resisting glazing. Picture frames and models sit at 2–3 mm in UK trade guides. Plastics, and do not agree on one millimetre. Extruded is the cheaper forming grade, with a tighter thickness tolerance that quotes from ISO 7823-2 as plus or minus 5 percent from 3 mm.

Personal buying guide
Question 1 of 2
What are you covering?
The GSHUR 580 × 430 mm sheet is stated at 3 mm and £13.99, with 4.7 from 50 ratings. That is the highest star line in the set, on a small sample. Fourteen of the 22 review texts in the file are from the United Kingdom, and they use the sheet for shed and playhouse windows. Buyers who peel the film call it clear, and one cut it with the film left on. One buyer, after a film they described as one-sided, called the sheet smoked rather than like the photos. Another review mentions 5 mm, while the listing stays at 3 mm. The bullets claim UV resistance without a weathering test. A 4.7 on 50 ratings does not make this the top pick ahead of the 610 mm pane with 380 ratings.
Pros
Cons
Best for: Your opening is about 580 × 430 mm, and you will peel the film before you judge the colour.
Less suitable: You are choosing on the star line alone, or you measured a 610 mm greenhouse bar.
Specifications
Common questions
Is it 5 mm?
The listing says 3 mm. One UK review mentions 5 mm. The recorded thickness stays 3 mm.
Is it as clear as the photos?
Several UK reviews say it is clear after the film is removed. One buyer called it smoked after peeling a film.
PIANKEKE's pack is thirty 10 cm squares at £9.69, with 4.6 from 394 ratings. The listing thickness is 0.1 cm, about 1 mm, and the printed item weight is 5 g for the pack, which is not a figure to use for density. UK reviews praise the price, a uniform size for 3D-printed photo frames, and clarity once both films are off. They also call the squares quite thin, the edges slightly rough, and the film hard to start. Buyers have used them as coasters with a cork back and as cards between two squares. They wash with water. They are craft blanks, not a glazing pane.
Pros
Cons
Best for: You want 10 cm craft blanks, palettes, or small frame inserts and you accept a 1 mm gauge.
Less suitable: You are glazing a window, or you need a sheet that feels sturdy in the hand.
Specifications
Common questions
Are they thick enough for glazing?
Reviews call them quite thin. The listing thickness is 0.1 cm. They are sold as craft panels, not greenhouse panes.
Why do they look dull?
UK reviews say film on both sides makes them look opaque until it is peeled.
Sheetcuts' 610 × 610 mm sheet is the top pick in this set for a side pane whose bars match that size. The listing and the dimension line both say 610 × 610 × 3 mm, the captured price is £13.99, and the amazon.co.uk line is 4.6 from 380 ratings. That is the largest count among the greenhouse panes here. The listing ranks first in Greenhouse Covering Plastic in this capture and claims UV resistance, which is a bullet rather than a weathering test. UK reviews describe storm-broken greenhouse glass and some shed glass replaced with a lighter sheet, and an exact fit when the bars matched. The same reviews report sag where a roof pane meets glass, and a Stanley-knife cut that cracks the sheet. A blue tint, or a sheet that is not clear, turns up for some buyers. There is no frame in the box.
Pros
Cons
Best for: You measured a 610 mm side pane, you will cut with a saw, and you are not using the sheet as an unsupported roof.
Less suitable: You measured 600 mm, you need a curve, or you cannot accept flex on a roof.
Specifications
Common questions
Will 3 mm stay flat on a greenhouse roof?
UK reviews include sag where the pane meets glass, and buyers who found it too flexible for a roof versus a side.
Can you cut it with a Stanley knife?
A UK review calls that claim misleading. Other reviews cut it with a saw or jigsaw.
Sheetcuts lists this pane at £15.95 with 4.6 from 110 ratings. The title and the dimension line say 610 × 457 × 3 mm, while a bullet says 600 × 600 mm, so the page does not agree with itself. UK reviews still describe shed windows, greenhouse glass, and a playhouse, plus one splash panel behind a bin after a cut. One buyer's micrometer read under 2.5 mm against the 3 mm claim. Another says the sheet will not bend to a curve, and one called it very fragile and would choose thicker next time. The printed weight is 1 kg, lighter than the 1.7 kg on the 610 mm square in this set. A review titled Real Lexan is the buyer's guess. The listing says acrylic.
Pros
Cons
Best for: You have measured 610 × 457 mm, and you will check the sheet against that rectangle when it arrives.
Less suitable: You needed a 600 mm square, a curve, or a thickness you have confirmed with a micrometer.
Specifications
Common questions
What size is it?
The title and the dimension line say 610 × 457 × 3 mm. A bullet says 600 × 600 mm. Measure against your rebate.
Is the thickness a full 3 mm?
The listing says 3 mm. One UK review reports a micrometer reading under 2.5 mm.
The GSHUR two-pack is two A4 sheets stated at 210 × 297 mm and 3 mm, at £6.99, with 4.5 from 1,156 amazon.co.uk ratings. That is the largest review count in this set, and UK buyers use the sheets for picture-frame glass, a clock face, a small fish-tank top, and paint palettes. Several say a cut is clean for a frame or a calendar, and that the sheet looks like glass once both films are off. The material field is printed as Plastic while the bullets say acrylic, and cast or extruded is not stated. One buyer decided the sheets were not cast acrylic after laser attempts failed. Scratches come up, some buyers still find the sheet not clear enough for a photo, and a chipped corner arrived still usable. It is the best value here when the rebate is A4 and 3 mm fits the lip.
Pros
Cons
Best for: You are replacing A4 picture-frame or clock glass at 3 mm, and you will peel both films before you judge the clarity.
Less suitable: You need a named cast sheet for a laser, or a pane larger than A4.
Specifications
Common questions
Is this pack A4 and 3 mm?
The listing states 210 mm × 297 mm and 3 mm thickness, two sheets, at £6.99.
Why might the sheet look frosted?
The listing says there is protective film on both sides, and UK reviews say the sheet looks clear after that film is peeled.
Pixly's captured variant is one 5 mm A4 sheet, 210 × 297 mm, at £7.99, with 4.5 from 536 ratings. The title also lists A5, A4, and A3, plus 2 mm, 3 mm, and 5 mm. A UK review says you still receive one sheet of the variant you chose. Buyers describe a thick feel, cuts and drilled holes for a cracked glass panel and a summerhouse pane, and use as a watercolour board and a dry-wipe fridge board. The bullets say smooth polished edges, while UK reviews also report a sharp burr. Film on both sides makes the sheet look translucent until it is peeled, and one buyer did not find it crystal clear. Cast or extruded is not stated, and the printed weight is 360 g.
Pros
Cons
Best for: You want a stiffer A4 cover than the 3 mm pair, and you will deburr the edge.
Less suitable: You expected several sheets in one box, or a greenhouse-sized pane.
Specifications
Common questions
How many sheets are in the box?
Number of items is 1. A UK review says the multi-size title still ships a single sheet of the chosen variant.
Are the edges polished?
The bullets say smooth polished edges. UK reviews also report a sharp burr.
Taiyeestar's pack is ten sheets stated at 1 mm and 10 × 15 cm, at £6.99, with 4.5 from 419 ratings. UK buyers use them for craft, stencils, and photo-frame glass, and one recut a ring-doorbell lens cover. A blade cut is a repeated point of praise, and the sheet is described as clear after the film is peeled. The title says square while the stated size is rectangular, and the dimension line prints a 1 cm height against a 1 mm thickness. One buyer found the sheets semi-opaque and unsuitable for picture frames. The film is fiddly and makes an unpeeled sheet look like the wrong product. The material field is empty; the bullets say acrylic.
Pros
Cons
Best for: You want small craft blanks or a cheap frame glass you can trim with a blade.
Less suitable: You need a square blank, or a pane that stays fully clear in a frame.
Specifications
Common questions
Are these square?
The title says square. The stated size is 10 × 15 cm, which is rectangular.
Will they replace picture-frame glass?
The listing names picture-frame glass. UK reviews include successful frame swaps and one buyer who found them semi-opaque.
The Art3d five-pack is £7.99 for five sheets stated at 8 × 10 inch and 1 mm, with 4.5 from 41 ratings. The title says acrylic. A listing bullet says recyclable PET, and a verified UK review on 5 August 2026 states the sheets are PET, not acrylic. Buyers who peeled both films call them clear, and one used a sheet as a kitten splash guard. The same review set says the sheets were no good for laser cutting or printing. One buyer had to cut them down because they were slightly too big for the frames. Only nine review texts sit in the file, eight of them from the United Kingdom. Buy this pack only if the job is a thin PET cover, not PMMA.
Pros
Cons
Best for: You want a thin PET cover, you have read the material conflict, and you can trim the 8 × 10 inch sheet.
Less suitable: You need acrylic, a laser cut, or an exact frame fit without trimming.
Specifications
Common questions
Is this acrylic?
The title says acrylic. A listing bullet says PET sheet, and a verified UK review on 5 August 2026 states the sheets are PET, not acrylic.
Can it be laser cut?
The listing names a laser. A verified UK review says it was no good for laser cutting or printing.
This Sheetcuts pane is a single 600 × 600 mm sheet stated at 3 mm, at £15.95, with 4.4 from 57 ratings and a printed weight of 1.7 kg, and there is no frame. UK reviews include a greenhouse opening window and a jigsaw trim for a garage window, and buyers who wanted something safer to handle than glass where children are about. The repeated fault is length: reviews describe a shortfall of about 10 mm on width and length, so the rubber was not covered, and one buyer averaged about 605 mm and said 5 mm is critical. A 600 mm sheet is not a 610 mm greenhouse module. One review could not cut it cleanly and fitted it with cracks. A review cites £18.75, while the stored header price is £15.95.
Pros
Cons
Best for: You measured a rebate that can take a pane a few millimetres under 600 mm, and you will saw it rather than score it.
Less suitable: You need 610 mm in the bar, or a cut you expect to finish with a knife.
Specifications
Common questions
Does it include a frame?
No. The listing is a sheet only, and the bullets do not include a frame.
Will 600 mm fit a 610 mm greenhouse bar?
UK reviews say a shortfall of about 5–10 mm left gaps at the rubber. Measure the rebate.
dabinzhijia sells six 20 × 30 cm sheets stated at 2 mm for £10.99, with 4.2 from 196 ratings and a printed weight of 760 g. UK reviews mention a 10 W laser, a CO2 laser, and a Cricut Maker 4. The listing calls the acrylic UV-resistant and says it will not yellow. That is a bullet, not a weathering test. Buyers who left the film on thought the sheets were frosted. Cast or extruded is not stated, so those laser reports are not a grade certificate. Several reviews mention neat edges and wrapping that arrived intact. The technical block does not print a dimension line.
Pros
Cons
Best for: You are cutting small 2 mm blanks and you already know a similar sheet works on your laser or Cricut.
Less suitable: You need a named cast grade, or a sheet sized to a greenhouse rebate.
Specifications
Common questions
Is the frosted look the real surface?
UK reviews say a frosting layer is protective film and the sheet is clear after peeling.
Have buyers laser-cut it?
UK reviews mention a 10 W laser, a CO2 laser, and a Cricut Maker 4. Cast or extruded is not stated.
ASelected's pack is two A2 sheets stated at 594 × 420 mm and 2 mm, at £16.99, the highest price in this set, with 4.1 from 38 ratings. Eight review texts are in the file, all from the United Kingdom. One buyer cut the 2 mm sheet with a Stanley knife for an aquarium lid that did not bow. The repeated complaint is the corner. Both sheets were damaged on the same corner in more than one order, including a second replacement. One buyer still cut a usable piece of about 20 × 15.5 inches from a damaged sheet. The dimension line prints 59.4 × 42 × 59.4 cm, which repeats the length and fights the 2 mm thickness. The listing's impact claim is not a test.
Pros
Cons
Best for: You need A2 at 2 mm, and you can return a sheet that arrives with a cracked corner.
Less suitable: You need both sheets intact for a full A2 job, or a 3 mm greenhouse pane.
Specifications
Common questions
Can 2 mm be cut with a knife?
A UK review cut this 2 mm sheet with a Stanley knife for an aquarium lid. The listing also names a saw and a drill.
Do the corners arrive intact?
Not in every review. More than one UK buyer reports corner damage, including a repeat order.
GSHUR's single 50 × 50 cm sheet is stated at 3 mm and £13.99, with 4.1 from 29 ratings. Twelve review texts are in the file, seven of them from the United Kingdom. Those UK reviews include a jigsaw cut and drilled holes for a temporary window, a shed window, and a picture-frame glass swap where the dimensions matched. A chipped corner on arrival is the transit complaint. Scratches once the film is off are called the weak side of this plexiglass. The material field says Plastic and the bullets say acrylic. The catalogue has no full dimension line, only a 50 cm diameter field. The listing's line of 18 times ordinary glass is not a test in this file.
Pros
Cons
Best for: You want a 500 mm square at 3 mm for a shed pane or a large frame, and you will check the corner on arrival.
Less suitable: You want a large review sample, or a 610 mm greenhouse module.
Specifications
Common questions
Can it be cut and drilled?
A UK review reports a jigsaw cut and drilled holes for a temporary window. The listing also names saws and a drill.
Does it arrive undamaged?
Not always. A UK review reports a chipped corner. Other UK reviews praise the packaging.
Shelf prices, sizes and star lines are the figures stored from the twelve amazon.co.uk listings in this set, read on 19 October 2026. Review points come from the notes for those ASINs. This is not a lab test. A millimetre is the seller's claim unless a UK review measured otherwise, and that measurement is one buyer's reading. Where the title and a bullet disagree, both stay in the record and the conflict is a deduction. Cast versus extruded is not stated on these ASINs, so it is not scored as a grade. The highest score is the top pick. Best value is the A4 pair with the largest review count at the lowest stored price for 3 mm A4, and it does not also take the top score.
Amazon evidence
25%Star rating on amazon.co.uk, then the review count. A 4.5 from 1,156 or a 4.6 from 380 fills this block. A 4.7 from 50 does not, because the sample is small.
Spec agreement
25%Acrylic named without a fight, one thickness, and size lines that match. A PET bullet under an acrylic title, a 600 mm bullet on a 457 mm pane, and a dimension line that repeats 59.4 cm are deductions.
Review outcome
30%UK comments that match the stated job: a 610 mm side, an A4 frame, a small laser blank. Roof sag, a short rebate, a cracked corner, and a failed laser cut are deductions.
Value
20%Stored GBP for the job you are actually buying. £6.99 for two 3 mm A4 sheets scores as value for frames. It does not also take the top score, because an A4 pair is not the greenhouse pane.
Buy the job and the rebate before the word acrylic. A pane on amazon.co.uk may be a 1 mm craft pack, an A4 frame sheet, or a single 3 mm greenhouse pane, and they are not substitutes. 600 mm and 610 mm are both sold, and they do not swap. Peel both films before you judge clarity. A title that says acrylic can still be PET. None of these listings is fire-resisting glazing.
An acrylic glass pane, for a UK shopper, is a flat clear sheet of PMMA sold as acrylic, Perspex or plexiglass, used in place of glass for frames, craft, sheds and greenhouse repairs. The twelve amazon.co.uk listings in this set run from 1 mm craft packs around £7 to single 3 mm panes around 600 mm at about £13.99 to £15.95. Quality is the stated thickness, the measured size against the rebate, and whether the sheet is actually acrylic.
Film on both sides is normal. UK reviews repeatedly say the sheet looks frosted, dull or smoked until both faces are peeled. Peel it before you decide the sheet is the wrong product.
600 mm and 610 mm are both sold as greenhouse panes. Reviews on the 600 mm Sheetcuts sheet include shortfalls of about 5–10 mm that missed the rubber. Measure the rebate in millimetres.
A title that says acrylic can still be PET, as on the Art3d pack. A Stanley-knife claim on the 3 mm 610 mm sheet is called misleading in a UK review. A 3 mm greenhouse pane often needs a fine saw. Do not use glass cleaner.
The first check is the opening, not the word pane. Picture frames and models sit at 2–3 mm in UK trade guides. Shed and greenhouse wall panes are often quoted at 3 mm up to about 600 mm, or 4–5 mm when the pane is larger, on a roof, or exposed. Plastics Direct, Plastic Sheets Direct and Plastic Sheets Shop do not agree on one millimetre, so this page does not pretend they do.
Ask for acrylic or PMMA. Polycarbonate is tougher and scratches more easily. PET is a different sheet. The Art3d five-pack is titled acrylic while a listing bullet and a verified UK review on 5 August 2026 say PET, and a laser cut was reported as unsuccessful. Cast versus extruded is not stated on these ASINs. Cast is the laser-friendly grade in Perspex's description.
Three typical situations, each with a recommendation from this comparison.
You are replacing storm-broken glass and you have measured a 610 mm side. The Sheetcuts 610 × 610 mm sheet at 3 mm is the top pick, about £13.99, with 4.6 from 380 ratings. UK reviews report a fit when the bars match. At 3 mm it can sag on a roof, and a Stanley knife cracks it. Cut with a saw.
You want A4 picture-frame or clock glass at 3 mm, and you will peel both films before you judge the clarity. The GSHUR two-pack is best value at about £6.99, with 4.5 from 1,156 ratings. The material field says Plastic. It is not a named cast sheet, and it is not larger than A4.
You are cutting small 2 mm blanks and you already know a similar sheet works on your laser or Cricut. UK reviews of the dabinzhijia six-pack name a 10 W laser, a CO2 laser and a Cricut Maker 4. Cast or extruded is not stated. Do not buy the Art3d pack for that job: a UK review identifies it as PET.
The top pick is the Sheetcuts 610 × 610 mm sheet at 3 mm, about £13.99. It scores 84, the highest here: the title and the dimension line agree, and the amazon.co.uk line is 4.6 from 380 ratings. UK reviews report a fit when the bars match. Roof sag at 3 mm, and a Stanley knife that cracks the sheet, are the deductions. Best value is the GSHUR two-pack of A4 sheets at 3 mm, about £6.99, with 4.5 from 1,156 ratings, the largest count in the set. The material field says Plastic, and it is not a greenhouse pane. The Art3d five-pack does not take a badge: the title says acrylic, while a bullet and a UK review say PET.
GSHUR A4 acrylic sheets, 3 mm, pack of 2
About £6.99 for two 3 mm A4 sheets, with 4.5 from 1,156 ratings. The material field says Plastic.
