Head-to-head

Thule Force 3 L vs Force 3 XL: XL adds ski length and volume but tightens the hatch-clearance requirement

The short answer

Choose Force 3 L for shorter skis and a lighter box on a tighter roof. Choose Force 3 XL when 18 cubic feet or skis up to 200 cm are necessary. Both use the same published bar-spacing range, but the XL adds length, weight and a stricter hatch-clearance requirement.

Before you choose

The reasoning and the trade-offs

The ski limit is the clearest upgrade boundary

A 190 cm ski fits only the XL's published length limit.

What this is based on

190 exceeds the L's 175 cm limit and is below the XL's 200 cm limit. This assumes the complete load fits and the box is installed correctly.

Main trade-off

Cannot accommodate skis over 175 cm

About this comparison

Compare Force 3 L and XL for 175 versus 200 cm skis, cargo volume, roof-load allowance and hatch clearance. Check the measurements before upsizing.

Choose Force 3 L for shorter skis and a lighter box on a tighter roof. Choose Force 3 XL when 18 cubic feet or skis up to 200 cm are necessary. Both use the same published bar-spacing range, but the XL adds length, weight and a stricter hatch-clearance requirement.

Winner by situation

What matters in practice

The differences that matter

The ski limit is the clearest upgrade boundary

A 190 cm ski fits only the XL's published length limit.

How we reached this conclusion

190 exceeds the L's 175 cm limit and is below the XL's 200 cm limit. This assumes the complete load fits and the box is installed correctly.

Extra volume also consumes roof capacity

XL adds 12.5% volume and 6.6 lb of box weight.

How we reached this conclusion

(18 − 16) ÷ 16 = 12.5%. Manual weights give 49.6 − 43 = 6.6 lb that cannot be used for cargo under the same roof-load ceiling.

The hatch check can block the upgrade

A 52-inch Thule front-clearance measurement clears L's threshold but not XL's.

How we reached this conclusion

52 is greater than 50.625 and less than 53.0625 inches. Final fit still includes the specified bar and clamp checks.

What you give up

Every choice has a cost

If you choose Thule Force 3 L

  • Two cubic feet less cargo volume

If you choose Thule Force 3 XL

  • Needs more hatch clearance and eight inches more body length

Recommendation switch

The decision flips if...

Your skis exceed 175 cm but not 200 cm

Choose Thule Force 3 XL. XL is the only model whose published ski limit covers them.

Your Thule hatch measurement passes L but falls below XL's threshold

Choose Thule Force 3 L. The larger box cannot be assumed to clear the hatch.

Your fixed bar spread exceeds 36 5/8 inches

Choose neither. Both fail the published spread range.

What matters in practice

How to make the call

01

Measure the longest item first

A 190 cm ski makes the smaller box unsuitable regardless of how much empty volume remains. If every item fits within L's dimensions, the larger shell is optional rather than an automatic improvement.

02

Check the hatch with the correct reference

Thule's method measures from the front bar center to the point where the roof meets the hatch. The product and chart have small rounding differences, so the more conservative values are used here. Trial-check opening clearance after installation.

03

Calculate the usable load

The box's 165 lb cargo limit is only one ceiling. Vehicle and rack limits may be lower and include the rack and box themselves. More cubic feet can help bulky bedding while adding little useful capacity for dense equipment.

Check these before buying

  • Measure approved bar-center spacing and confirm bar profile against the mounting instructions.
  • Use the stated Thule hatch method and the stricter threshold shown here.
  • Add rack, box and cargo weights and remain below every applicable limit.
  • Force XL height differs between the current page and manual, so verify installed height before entering a garage.

What this comparison cannot tell you

  • No vehicle is declared universally compatible. Published volume does not establish how a particular suitcase set will fit.
