At 18\", it accommodates blocks up to 17.5\" finished (18\" unfinished) in a single placement.\u003c\/p\u003e\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\u003cdl\u003e\n\u003cdt\u003eWhat blocks require the 18\" square?\u003c\/dt\u003e\n\u003cdd\u003e16\" finished blocks (16.5\" unfinished), 17\" finished blocks (17.5\" unfinished), and any oversized block trimming task where the 10.5\" square would be too small. Also useful for squaring up large quilt units before assembly.\u003c\/dd\u003e\n\u003cdt\u003eIs the 18\" square necessary if I have the 10.5\" square?\u003c\/dt\u003e\n\u003cdd\u003eFor blocks larger than 10.5\", yes — the 18\" square is the only QS ruler that handles the largest standard block sizes. The 10.5\" and 18\" squares complement each other across the full range of block squaring tasks.\u003c\/dd\u003e\n\u003cdt\u003eCan the 18\" square be used for backing fabric preparation?\u003c\/dt\u003e\n\u003cdd\u003eYes — an 18\" square makes an excellent reference tool for squaring up large backing fabric sections and checking that backing pieces are cut accurately on grain.\u003c\/dd\u003e\n\u003cdt\u003eIs the non-slip coating effective at 18\"?\u003c\/dt\u003e\n\u003cdd\u003eYes — same non-slip system as all QS rulers.
