Roman Blind vs Roller Blind: Fabric, Cost & Construction Compared

Updated: May 27, 2026

The Core Difference

A roller blind rolls up onto a tube at the top — the fabric must be stiff enough to roll without wrinkling, which usually means a coated or backed material.

A roman blind folds up in horizontal pleats — the fabric can be soft, patterned, or any weight, because the fold structure holds it in place. This is why roman blinds are more common in DIY sewing projects: any upholstery-weight fabric works.

Fabric Requirements Compared

For a 90 cm wide × 120 cm drop window:

Blind Type	Face Fabric Needed	Notes
Roller blind	1.30–1.40 m (1.42–1.53 yd)	Drop + 15–20 cm wind-up allowance
Flat roman blind	2.31 m (2.53 yd)	Drop + fold allowance + hems
Cascade roman blind	2.79 m (3.05 yd)	More fold allowance than flat

Roman blinds use significantly more fabric than roller blinds for the same window. The fold allowance adds 60–150 cm to the cut length depending on fold count and depth.

Fabric Type Requirements

Property	Roller Blind	Roman Blind
Fabric weight	Light–medium (not heavy)	Medium–heavy recommended
Stiffness	Required — or add blackout lining	Not required
Pattern direction	Matters — prints distort on a roll	Matters — pattern shows flat
Stretch	Must be minimal	Must be minimal
Appropriate fabrics	Purpose-made roller fabric, coated cotton	Canvas, linen, cotton sateen, velvet, chintz

Roman blind advantage: Virtually any non-stretch upholstery fabric works. Roller blinds are fussier — either use purpose-made roller fabric or add a stiffening backing before cutting.

Cost Comparison: DIY

For a standard bedroom window (90 cm × 120 cm):

	Roller Blind DIY	Flat Roman Blind DIY
Face fabric (at £15/m)	£20–£25	£35–£40
Lining (if applicable)	N/A or blackout backing	£15–£20
Hardware	Roller mechanism kit: £8–£15	Batten, rods, rings, cords: £10–£18
Total DIY	£30–£40	£60–£80

Roman blinds cost more to DIY primarily because of the additional fabric (fold allowance) and the extra hardware (rods for each fold).

Construction Complexity

Roller blind:

Cut fabric to width + 2 cm, length = drop + roll-up allowance
Hem the bottom
Attach to roller tube with double-sided tape or velcro
Insert into brackets

Flat roman blind:

Cut fabric and lining to precise dimensions
Sew side and bottom hems
Attach lining (slip stitch or machine)
Sew rod pockets at each fold line
Thread rings and cords
Staple to batten
Thread cords through rings and cord lock

Construction time estimate:

Blind	Experienced Sewer	Beginner
Roller blind	30–60 minutes	1–2 hours
Roman blind	2–4 hours	4–8 hours

Roman blinds have more steps and more precision required — fold lines must be straight and evenly spaced. See How to Calculate Roman Blind Folds for fold count and spacing.

Which to Choose: Decision Guide

Situation	Better Choice
Budget priority	Roller blind
Prefer soft, luxurious look	Roman blind
Patterned fabric you love	Roman blind (pattern shows fully)
Bedroom, formal sitting room	Roman blind
Kitchen, utility room, bathroom	Roller blind (wipe-clean easier)
Very large windows (over 200 cm wide)	Roller blind (roman joins become complex)
First blind-making project	Roller blind
Want blackout	Either (with correct lining/fabric)

Bold = most common context where roman is preferred.

Blackout: Roman vs Roller

Both can achieve blackout, but the method differs:

Roller blind blackout: Use blackout roller fabric (purpose-made, coated). Very effective — essentially zero light leak through the fabric itself.

Roman blind blackout: Use a blackout lining (Blackout Sateen or similar) behind the face fabric — see the Roman Blind Lining Guide for lining types and cut sizes. Light may still leak at the side hems and batten edges unless the blind exactly fills a recess.

Result: For complete light exclusion, roller blinds with blackout fabric are slightly more effective. Roman blinds with blackout lining are good but rarely achieve 100% blackout unless fitted into a recess that seals the edges.
