Below is a step-by-step way to estimate how many meters of 3100‑mm‑wide banner material you will need, including the extra “sew margins,” and while trying to nest smaller panels into the leftover space of bigger panels. This is a “rough” calculation but should be close enough for planning purposes.




1. Understand the Panel Dimensions and Margins​


  1. Finished (visible) height of each panel = 3900 mm
  2. Finished (visible) widths (there are 8 total):
    • 300 mm
    • 7850 mm
    • 5720 mm
    • 4900 mm
    • 5000 mm
    • 5700 mm
    • 7250 mm
    • 300 mm
  3. Extra margins to add for each panel:
    • Height margin: +50 mm top and +50 mm bottom = +100 mm total
    • Width margin: +150 mm left and +150 mm right = +300 mm total

Hence, each panel’s print size (the size you must print before sewing) is:


  • Print Height = 3900+50+503900 + 50 + 50 = 4000 mm
  • Print Width = (finished width)+300\text{(finished width)} + 300



2. Adjusted (Print) Widths​


Let’s list each panel’s “print width,” i.e., finished width + 300 mm margin:


  1. 300 + 300 = 600 mm
  2. 7850 + 300 = 8150 mm
  3. 5720 + 300 = 6020 mm
  4. 4900 + 300 = 5200 mm
  5. 5000 + 300 = 5300 mm
  6. 5700 + 300 = 6000 mm
  7. 7250 + 300 = 7550 mm
  8. 300 + 300 = 600 mm

All panels are 4000 mm tall (after adding the 100 mm height margin).




3. Why We Must “Tile” (Split) Large Panels​


Your printer is 3100 mm wide. Any banner piece whose print‐width exceeds 3100 mm must be split (tiled) into multiple vertical strips, then stitched together.


  • Each “strip” you print will be 3100 mm wide (maximum) × 4000 mm high.

Counting how many strips per large panel​


To find how many 3100‑mm‐wide strips are needed for a given print width WW:


  1. Number of strips = ⌈W/3100⌉\lceil W / 3100 \rceil (ceiling of W/3100W/3100)
  2. Once you split WW into that many strips, the final strip often has leftover space because 3100 × (number of strips) may exceed WW. That leftover space can sometimes be used for smaller panels.

Let’s go panel by panel (focusing on the wide ones > 3100 mm):


PanelPrint Width (mm)Strips NeededComputation
#2815038150 / 3100 ≈ 2.63 → ceiling → 3 strips
#3602026020 / 3100 ≈ 1.94 → ceiling → 2 strips
#4520025200 / 3100 ≈ 1.68 → ceiling → 2 strips
#5530025300 / 3100 ≈ 1.71 → ceiling → 2 strips
#6600026000 / 3100 ≈ 1.94 → ceiling → 2 strips
#7755037550 / 3100 ≈ 2.44 → ceiling → 3 strips

Small panels ≤3100\le 3100 mm wide:


  • #1 = 600 mm
  • #8 = 600 mm

Those two can fit into leftover space from the big panels’ final strips—thus (ideally) not increasing the total strip count.




4. Figuring Out “Leftover” Space in the Last Strip of Each Big Panel​


When you tile a wide panel, you essentially fill columns of 3100 mm. For example:


  • For #2 (8150 mm total width, needing 3 strips):
    • 2 full strips of 3100 mm each = 6200 mm covered
    • Leftover needed = 8150 - 6200 = 1950 mm
    • That 1950 mm goes into the 3rd strip, leaving (3100 - 1950) = 1150 mm free in that 3rd column.

We can use that 1150 mm leftover for smaller pieces (like a 600 mm panel).


Summaries of leftover for each big panel’s final strip:​


  1. #2 (8150 mm)
    • 3rd strip uses 1950 mm → leftover = 3100 - 1950 = 1150 mm
  2. #3 (6020 mm)
    • 2nd strip uses 6020 - 3100 = 2920 mm → leftover = 3100 - 2920 = 180 mm
  3. #4 (5200 mm)
    • 2nd strip uses 5200 - 3100 = 2100 mm → leftover = 3100 - 2100 = 1000 mm
  4. #5 (5300 mm)
    • 2nd strip uses 5300 - 3100 = 2200 mm → leftover = 3100 - 2200 = 900 mm
  5. #6 (6000 mm)
    • 2nd strip uses 6000 - 3100 = 2900 mm → leftover = 3100 - 2900 = 200 mm
  6. #7 (7550 mm)
    • After 2 strips of 3100 each (6200 mm), the 3rd strip uses 7550 - 6200 = 1350 mm → leftover = 3100 - 1350 = 1750 mm

Small panels (#1 and #8 are each 600 mm wide)​


  • We can tuck Panel #1 (600 mm)into leftover from #2’s last strip (1150 mm leftover)
    • That leaves 1150 - 600 = 550 mm leftover in #2’s final strip
  • We can tuck Panel #8 (600 mm)into leftover from (say) #4’s last strip (1000 mm leftover)
    • That leaves 1000 - 600 = 400 mm leftover in #4’s final strip

Because these two smaller panels fit into leftover space of the already‐required strips, they do not force any additional strips to be printed.




5. Total Strip Count and Total Length​


Now let’s count how many 3100‑mm‐wide strips we must run off the printer, panel by panel:


  • Panel #2 → 3 strips
  • Panel #3 → 2 strips
  • Panel #4 → 2 strips
  • Panel #5 → 2 strips
  • Panel #6 → 2 strips
  • Panel #7 → 3 strips
  • Panel #1 and #8 → tucked into leftover (so 0 “extra” strips)

Summing those:

3+2+2+2+2+3  =  14  strips total3 + 2 + 2 + 2 + 2 + 3 \;=\; 14 \;\text{strips total}
Each strip is:


  • 3100 mm wide (the full printer width), and
  • 4000 mm tall (the print‐height including the 100 mm margin).

Because you print them one “column” after another along the length of your roll, the total needed “length” on the roll is:

14⏟strips×4000 mm⏟height each=56,000 mm=56 meters of length\underbrace{14}_{\text{strips}} \times \underbrace{4000\,\text{mm}}_{\text{height each}} = 56{,}000\,\text{mm} = 56\,\text{meters of length}


6. Sanity Check by Total Printed Area​


  • Each strip is 3100×4000=12,400,000 mm23100 \times 4000 = 12{,}400{,}000 \text{ mm}^2 = 12.4 m²
  • With 14 strips: 14×12.4 m2=173.6 m214 \times 12.4\text{ m}^2 = 173.6\text{ m}^2
  • Dividing by roll width (3.1 m) → indeed about 56 m of length.

(If you simply summed all individual panel areas without any constraints, you’d get a slightly smaller area, but once we factor in that each wide piece must occupy full‐width “tiles” of 3100 mm, we pick up some unavoidable waste. Tucking the two 600‑mm panels into the leftover spaces helps a bit, but does not reduce the total number of strips needed.)




7. Final Answer (Roughly)​


  1. You will end up printing 14 “columns” (strips) in total.
  2. Each column is 4000 mm high, so the total roll length required is about 56 meters of 3100‑mm‑wide banner material.

That should be a good planning number (plus a small safety margin if you like). You have successfully minimized waste by nesting the two small panels (#1 and #8) into unused space in the larger panels’ last columns, so you do not need extra strips beyond these 14.

    • Width margin: +150 mm left and +150 mm right = +300 mm total

Hence, each panel’s print size (the size you must print before sewing) is:


  • Print Height = 3900+50+503900 + 50 + 50 = 4000 mm
  • Print Width = (finished width)+300\text{(finished width)} + 300



2. Adjusted (Print) Widths​


Let’s list each panel’s “print width,” i.e., finished width + 300 mm margin:


  1. 300 + 300 = 600 mm
  2. 7850 + 300 = 8150 mm
  3. 5720 + 300 = 6020 mm
  4. 4900 + 300 = 5200 mm
  5. 5000 + 300 = 5300 mm
  6. 5700 + 300 = 6000 mm
  7. 7250 + 300 = 7550 mm
  8. 300 + 300 = 600 mm

All panels are 4000 mm tall (after adding the 100 mm height margin).

    • That 1950 mm goes into the 3rd strip, leaving (3100 - 1950) = 1150 mm free in that 3rd column.

We can use that 1150 mm leftover for smaller pieces (like a 600 mm panel).


Summaries of leftover for each big panel’s final strip:​


  1. #2 (8150 mm)
    • 3rd strip uses 1950 mm → leftover = 3100 - 1950 = 1150 mm
  2. #3 (6020 mm)
    • 2nd strip uses 6020 - 3100 = 2920 mm → leftover = 3100 - 2920 = 180 mm
  3. #4 (5200 mm)
    • 2nd strip uses 5200 - 3100 = 2100 mm → leftover = 3100 - 2100 = 1000 mm
  4. #5 (5300 mm)
    • 2nd strip uses 5300 - 3100 = 2200 mm → leftover = 3100 - 2200 = 900 mm
  5. #6 (6000 mm)
    • 2nd strip uses 6000 - 3100 = 2900 mm → leftover = 3100 - 2900 = 200 mm
  6. #7 (7550 mm)
    • After 2 strips of 3100 each (6200 mm), the 3rd strip uses 7550 - 6200 = 1350 mm → leftover = 3100 - 1350 = 1750 mm

Small panels (#1 and #8 are each 600 mm wide)​


  • We can tuck Panel #1 (600 mm)into leftover from #2’s last strip (1150 mm leftover)
    • That leaves 1150 - 600 = 550 mm leftover in #2’s final strip
  • We can tuck Panel #8 (600 mm)into leftover from (say) #4’s last strip (1000 mm leftover)
    • That leaves 1000 - 600 = 400 mm leftover in #4’s final strip

That should be a good planning number (plus a small safety margin if you like). You have successfully minimized waste by nesting the two small panels (#1 and #8) into unused space in the larger panels’ last columns, so you do not need extra strips beyond these 14.

Who are we paneling?
some giant boutique that will go into construction and it's a pain in the ass (need to be installed in Jan 1st-2nd). I need to prepare the design, print it, stich the panels into the large banner, in 4 fucking days. Printing itself will take a day, and the corpos designer that probably will make it extra painful to extract it didn't send the design yet, and the stitching will take a day too. Basically I need to work up to 28th. FML.
